Unlike upstairs, about 8000 is enough to buy more than 20 points. 18K platinum is a little soft.

You'd better buy a 6-claw one. I just got engaged. My husband bought a 7800 2 1 900, H, VVS. I mainly look at appearance. See how you two choose more than 20 points to be collectible.

How to choose a wedding diamond ring

selection principle

There are four "C" principles in selecting diamonds: cut, color, clarity and carat weight. This is the key to identify the quality and value of diamonds.

incision

Cutting is the only human factor. A skilled diamond cutter can make a good diamond shine, and he can make the internal light reflect to the surface of the diamond to the greatest extent. The cutter must cut symmetrically, just like looking in the mirror.

A good mine may be abandoned because the cutter's skills are not in place. The ideal diamond should be round, with 58 clear cut edges, which can reflect light to the greatest extent. A high-quality diamond has high value, strong reflectivity and good symmetry, but its cutting is not perfect. Cutting an inferior diamond may be too deep or too shallow to make it shine because it wants to retain the maximum weight. Polishing technology will also affect the quality of diamonds. Perfect cut and symmetrical diamonds may reduce their value due to poor polishing.

colour and lustre

In some big jewelry stores, some diamonds are displayed for comparison. They arrange diamonds of various color grades in a row to help customers compare, because ordinary customers can't tell the color of diamonds with the naked eye. The color of diamonds is colorless as the top grade, and gradually comes second with the deepening of yellow.

pure

Generally speaking, defects determine the value of diamonds. More precisely, it depends on the impurity content in the drilled ore. Almost every diamond contains impurities, even the best quality diamond.

carat

Carat was once considered as the decisive criterion to measure the value of diamonds. When someone says that he bought a 2-carat diamond, people will find it unbelievable. In fact, the cut, color, purity and weight of a diamond are equally important to its value. The value of a 2-carat diamond with poor cutting technique, yellow color and defects is much lower than that of a perfectly cut, transparent and pure diamond. So the weight of a diamond is not the main factor that determines its value. The weight of a diamond still affects its value. It is important to find out whether the weight of diamonds told by jewelers is accurate. Therefore, when you buy a diamond, ask your jeweler to measure the weight of the diamond on the spot. If the jeweler doesn't want to do this, go to another store.

insertion

Mosaic is also an important part. Bad inlay will cause a lot of trouble and may make the diamond fall off. So when buying a diamond ring, be sure to check whether the bracket is firm and whether the joint with the diamond is thick enough.

shape

Now there are more and more styles on the market, and jewelry designers are constantly innovating. But the more classic styles are round, oval, pearl and square. Generally speaking, the shape of a diamond does not affect its value and quality. On the contrary, it reflects the original shape of the diamond before cutting.

Written explanation

Your diamond must have a certificate of authenticity, which explains the quality, weight and cutting process of the diamond. This is the guarantee for the diamond ring you bought.

Suggestion:

Try to choose diamonds above 0.20 carat, because only diamonds above 0.20 carat can begin to show the "fire color" of diamonds, and diamonds below 0.20 carat are too small to show the optical effect of diamonds. If you have the ability, you'd better buy diamonds with more than 25 points, and the "fire color" of diamonds with more than 25 points will begin to be obvious.

Avoid integer digits, such as 0.30 and 0.50. Think carefully when you buy it. Is it worth spending so much money to buy 0.0 Klado? However, you are unlikely to find stones with X8 and X9 scores, because the processor only needs to slightly modify the cutting angle and change it within the standard cutting range, so it can process stones with X8 and X9 scores cut by the extreme standard into diamonds with 30 scores less than the standard cutting, so the number X7 is chosen for insurance.

Guide to diamond grading certificate

You must have a grading certificate to buy diamonds.

Don't blindly pursue foreign grading certificates. I can say responsibly that China's grading standards are stricter than those of foreign countries, especially the definition and color grading. State inspectors and state leaders in Beijing can sometimes reduce the international certificate by 1-2. For example, a customer brought diamonds with GIA certificate classification of 50 points, VVS 1, F color and VeryGood cut, and cut them into 50 points, VS2, H-I color and VeryGood after classification in Beijing XXX Gemstone Testing Center.

There are two kinds of grading certificates:

1) bulk diamond classification certificate

2) Finished product grading certificate

Although both certificates are graded certificates, they are quite different.

1) weight

Diamonds classified by bare diamonds can be accurately weighed with a carat scale.

The grading of finished products can only estimate the weight according to the size of the diamond table (because it has been inlaid and the weighed weight is gold+diamonds, so it cannot be weighed), but the estimation is inaccurate after all (influenced by cutting work, the premise of estimation is extremely standard cutting work). If it's a 98-point stone, the mosaic grade is 1 carat, so you can't see that you wrote 2 points more, but according to the carat premium, the extra 2 points may cost you a lot of money.

2) clarity

The grading of bare diamonds means that the grader can observe diamonds from different angles with a gem microscope, which improves the chances of seeing all the tiny inclusions.

The graded diamond of the finished product has been embedded in the ring holder, and the grader can only observe it from the table, and may not see all the contents, and sometimes the contents of the diamond are just blocked by the metal clip embedded with the diamond, and can't be seen at all. Diamonds with pinnate (cracked) SI grade can be upgraded to VS or even VVS grade.

3) color

When grading a bare diamond, the grader observes the diamond from the table top and the bottom tip, and puts it on the diamond color chart for grading. Colorimetric stones are also generally used (as long as the color of the diamond is observed from the bottom tip).

The graded diamond of the finished product has been embedded in the ring holder, which can only be observed by the watch. The gold around the diamond will affect the judgment of the grader (the whiteness of the gold is not enough, which will reduce the visibility of the yellow tone of the diamond). The grading of finished products depends entirely on the experience of graders.

4) cutting

When grading bare diamonds, graders observe diamonds from all directions, and sometimes use cutting scales to grade them, with high accuracy.

The graded diamond of the finished product has been embedded in the ring holder, which can only be observed by the watch. The gold color around the diamond will affect the judgment of the grader, and it is impossible to accurately grade the cut (and lead to inaccurate weight estimation).

From the 4C classification above, we can see why the grading standard of finished diamonds in the national standard is much looser than that of bare diamonds, and the grading of finished diamonds is not very accurate, which mostly depends on the experience of graders.

Therefore, for the same diamond, the classification of the original stone is SI 1, H-I, with a score of 28, which is good for cutting.

The classification of finished products may be VS 1(VVS2), G(F), 30 minutes, and verygood cut.

Suggestion:

First of all, don't blindly pursue international certificates. Domestic grading standards are stricter than international ones.

Secondly, try to choose the original stone grading certificate. If you must choose the certificate of grading of finished products, please understand that even if your diamonds are of the same grade as the rough diamonds, the actual grade of the finished diamonds will generally be lower than that of the rough diamonds. (That is to say, the actual value of finished graded diamonds is generally lower than the actual value of graded diamonds with the same level of bare diamonds)

Commonly used diamond maintenance methods are as follows:

1, cleaning method of cleaning liquid

Fill a small bowl or teacup with warm water and mix a proper amount of neutral detergent in the water. Soak the diamond in water, brush it gently with a toothbrush, then wrap it with a sieve and rinse it with warm water under the tap. Finally, dry it with a soft cotton-free flannel.

2, cold water immersion method

Soak the diamond in water with a small bowl or teacup for about 30 minutes, then gently brush the diamond in front, back, left and right with a small brush, then shake it in water for a while, then take it out and dry it with a paper towel.

3. Quick cleaning method

Buy a bottle of brand-name jewelry cleaning solution, together with the attached container, and clean the diamonds according to the instructions.

The following are some tips to help you maintain diamonds.

Please don't get chlorine bleach on diamond jewelry when doing housework. Although it will not damage the diamond, it will make the inlay fade or change color.

Don't wear diamonds when washing dishes or doing rough work. Although the diamond is hard, it may be scratched if it is struck hard according to its grain direction.

6. Take your diamond jewelry to the jeweler once a year to check whether the inlay is loose and worn, and then fix and polish it again.

How to choose a diamond ring? I didn't intend to publish it online when I wrote this article a few days ago. I told you in private, but my kindness earned you a comment on my BS. I said I was jealous of how much money others earned, or I was too extreme. I decided to make a point. Every line has its own rules. What I said has touched the deepest part of this industry. I have entered this diamond industry for the eighth year. What I saw, heard and suffered. I won't just tell you the advantages of diamond, nor will I tell you its disadvantages. The following text will be updated frequently, and I will add everything I think. Yamaha, I just came to this forum and saw a lot of diamonds bought here, but there are also many problems. Everyone is getting married, and it will cost a lot. I don't want everyone to be cheated when shopping again. I can only give you some advice and attention on diamond trading. ! It's much cheaper for you to buy diamonds for fun. You all think you have taken advantage of them, don't you? In fact, only knowledgeable people can buy cheap, real and moisture-free diamonds. There's a lot of shady inside, you know? The diamond seller himself or his family is related to the appraisal station, and the price is% 100. In your opinion, the price is very cheap, and similar products are much cheaper than regular stores. But in my opinion, the profit is still a little. But this is normal, and it is understandable to make money in business. I will not say more about the specific profits. Because a seller may take a few more turns in the purchase channel to get a higher price ~ (except for the normal fees and procedures, hard work ...), how much to earn depends on people's conscience ... Take a seller who started his business very early as an example. She works in an appraisal station. How many people are there in the circle of Shanghai Appraisal Station? Not many people are employed, but many hold appraisal certificates. At the beginning, half of our class took the exam ~ in Shanghai, as long as they have a labor certificate, they can take the exam themselves. GIA has no organization, so she can't. Shanghai won the best H**. But when we were young, it was impossible for us to go to the appraisal station for jewelry majors. Locally speaking, the older the qualifications, the better ~ think for yourself ~ generally, these people are sold out of interest, and they are still. While raising the price, it also lowered the price. As soon as everyone compared, they all went to buy cheap ones. In fact, they are all one person. It's ok to sell expensive things in real time, but they are all average or inferior ~ ~ I looked at them some time ago and saw a proof: there are two colored inclusions under the countertop and extra facets below. Two of these three questions are SI, which is two grades behind his certificate. VS is also divided into 1 and 2 ~ 1. The inclusion is on the side and the inlay can be removed, but it is very small. 2 it is in an obvious place ~ the color can't be compared, there is no real thing. This drilling and cutting work is very general. What's more, as long as 58 faces are there, it depends on the fact that all faces in Shanghai are open to a good working proportion. It is not reflected in the certificate of Shanghai. GIA certificate is available, but now many domestic GIA are water, which will be explained in detail below! When buying a drill, don't buy a drill with an integer of 30 3 1 40 4 1. If this kind of drill is made according to standard workmanship, it will only be 27 ~ 28, 37 ~ 38. Drill above 0.80. There are few such goods on the market. More than 80 standard workers have been done, and most of them have been ground to 1 carat. This involves turning. You can estimate the output of a diamond by observing its shape before cutting. If it should be 27 ~ 28 37 38, it is necessary to ensure that the proofreading angle of each section is relaxed or deepened during cutting. The desktop is bigger. Thicker the edge ~ ~ so that the yield of the bit will go up. If you drill 28, it will be 30, and the selling price is a little cheaper than that of a regular worker with 30, and much more expensive than that of a regular worker with 28. This is why the price difference between the same level and the same size ~ ~ These are all rules and regulations ~ ~ The layman can't understand whether the specific section is standard or not, even if I show it to you with a magnifying glass. They only know to meet once, once. The layman wants to know if the lathe worker is turning. Give you some advice: you can look at the table, that is, the size of the equilateral octahedron on the top of the diamond should be about %60, and then look at the edge of the drill, that is, the maximum circular diameter, whether it is thick or not, that is, the angle is deep and the drill is long and heavy. If it affects the color ~ thin, it will be worn out accidentally when cutting. Some people may wear the edges. Just no edge, but not great. Strictly speaking, it should be re-sharpening. This will reduce the diameter of the circle and reduce the weight. He can roll the thin side directly in the edger without edging. If other edges don't scroll, some edges will appear. But in this case, the largest circle diameter will be bright. If the edges are not rolled up, they will become dull. Also, if the edge thickness is the same ~ ~, there will be a problem that the cutting is not in place. In this case, the diamond will not be very round ~ besides, the equilateral lines of the diamond are all equal in length and width. Because diamonds are all cut by hand, whether to estimate them in the cutting process depends entirely on the workers' eyesight. There seems to be no obvious surface size, and the length of the line is enough. You should buy a diamond with a mantissa of 3 4 5 67 8, but 9 is 10, but you should set it well, otherwise it will be exposed. Generally, it is sold separately in grades of 30 ~ 40 ~ 50 ~ 60, and not much in grades of 20~30, because we are wholesale. Otherwise, whoever sells well is less than 20 ~ ~, and they are all packaged and sold. A pack will give you the wholesale price. SI VS H I is separate, and you can sort it yourself when you buy it back. You can also choose H from the VS I colors in S I. Let's talk about the process of selling diamonds online: the process of selling diamonds is generally like this. Contact first, say hello to the buyer, and the seller will tell the price, if you are satisfied. Generally, only a few people with relatively large capital rent an office in the office building and make an appointment to see the goods in the customer's office. Such people have more diamonds in their hands, buy out a little by themselves, and pay more on credit ... If they don't have capital, they will ask their customers to find a place to meet casually. This kind of people don't buy out by themselves, but buy as much as they need, so they will go to their home to get a few of the same size for buyers to choose from (in fact, how many buyers choose? I only know it's bright. If you buy it, repeat the appraisal immediately before making the ring. If you can't do it, you should return it immediately ~ ~ ~ But there is one thing that many people won't meet you in a regular jewelry company, because they are all privately traded, because it is not done by this regular diamond company. It's impossible to take you to a regular diamond company to talk about it ~ the current job or the previous job of selling diamonds is related to the diamond industry. (* * * * * * * * * * * *) It doesn't matter whether you look at it or not. The customer believes in the certificate ~ I will accompany you to Huang Chengmiao for appraisal ~ (Many diamonds given to you by the seller are certified and opened in advance, so you are required to re-examine, because they are in the industry, so the appraisal standard is relatively wide. They are all high) or just give you bare diamonds without a certificate, and the seller will accompany you to identify them. In fact, she can't speak, but everyone at the appraisal station is tall. I'll give you a higher grade ~ because you're going to set it soon, the set diamond can be raised a little, because it's not a loose diamond, so the appraisal result is allowed to have a little error ~ if you re-examine, it's free. I just want to tell the appraiser to choose three. After appraisal, it does not meet the requirements of the buyer. Then I'll take one for identification. You think you buy food ~ identify the price of a loose diamond. I showed you three bad ones. Do it again. It should be said that the three pieces taken by the seller for the first time are really poor, and the appraisal place is embarrassed to drive up ~ ~ After the appraisal, the seller will take the buyer to the jewelry inlay department next to it to make a ring. (This place is generally unprofitable, and PT is genuine, not deceptive. ) The average female's work cost is 100, which is a little more complicated. I have not been there this week. But it must have gone up ~ it was 235 last month. The seller will let you authenticate again with the certificate just now, which is free ~ ~ She will say that it is safer to authenticate again after the diamond has passed someone else's hand, so you will be very grateful to her ~ ~ ~ Pay the money after passing the verification ~ ~ ~ There is only PT CT on the ring, and there is no company LOGO, because you can't knock on any company logo where you make the ring. It's illegal ~ Hey ~ ~ How happy you are when you pay ~ I think the diamonds I bought are really cheap and high-end ~ ~ But in fact ~ ~ you bought them cheaper than those in the store. But not the most cost-effective certified diamond. But if you take this loose diamond yourself and there is no seller to accompany you to identify it, don't try it with a certificate. It is unlikely that your own level will reach the level of the original certificate he gave you. For a stranger, it is very difficult to identify you at this level ... this is the so-called full escort service ~ ~ ~ All shoppers bargain, but this is a big taboo in this business. The price given by others is already quite low, and the requirements of buyers are still very high. What should I do? Ok ~ ~ I'll give it to you as you asked, and it's still the same price ~ ~ but I didn't give you the diamond she told you. Some people are not picky, as long as they are cheaper than outside. The certificate of diamonds bought by such people doesn't contain much water. For example, diamonds can be opened between ~ ~ H G. If it is a calm person, I will give it to him really ~ ~ If it is a counter-offer ~ ~ Of course, the price will go up. Oh, the wool is still on the sheep ~ I have written so much, which will definitely touch some people's interests. I hope you don't mind what you see ~ ~ After all, you have earned your money. So I can't make it too clear on the forum, and I don't want to leave my phone number ~ Although I don't know them, I am always suspected that I am jealous of others and others want to grab business. Those who buy and sell diamonds privately are all naked diamonds. Remove it? Then the labor cost is paid by itself, and the gold loss is counted as its own. This will cause a great loss, so the general sellers of loose diamonds are related to the people at the appraisal station, either knowing each other or knowing each other at home. So no matter how hard you try to identify it, it is useless. As long as he is around, as long as he knows in advance which appraisal station you are going to. But there is another way to identify the true level ~ Chenghuang Temple now has four nationally recognized identification stations. Generally, when buying diamonds, the seller provides diamonds, then carries them with him and issues a good certificate for you to re-inspect. If you re-examine with a certificate, you must write the appraisal grade on the certificate. Another is to give you diamonds, and I won't give you a certificate. I'll accompany you to the appraisal. You don't know which appraisal, he will recommend you to one, but this one must know someone, so when I saw that the appraisal place was brought by an acquaintance, I opened it up ~ ~ The safest thing is that you take the diamond yourself, don't ask for his certificate, find an appraisal home and don't tell him which appraisal you are going to, but you can't let him stay with you. They generally know 1~2, but they can't all know it. Even if there is, I don't know which one you want to go to. You asked them not to identify with you, so even if the people at the identification station knew them, they didn't see them, or they didn't receive the people who brought them to identify them. This appraisal place will give you an appraisal according to normal standards, and the pressure is great ~ ~ ~ ~ Generally G ~H can be opened, and when H is nervous, it will be opened for one year, ~ So if you really want to reach the level you require, the seller will have to give you a higher level of goods appraisal, but the price will go up again ... otherwise you will definitely not be able to reach it yourself. You can reach VS 65438+ by yourself. ! In addition, the people in the appraisal station also do the business of selling diamonds, but most of them just help their friends, ha ~ ~ So, only when they are out of sight can they identify the real grade ~ ~ In addition, if the diamond ring sold in the store is VS 1, then you can identify it yourself, that is, VS2 is the bottom grade, and so on. The color is the same. Next, let's talk about the appraisal institutions: China Gemstone Association (demolished) in the basement of Donghua Meizuan (now 6th floor) of National Light Industry Testing Station, 2nd floor of Yayijindian of National Light Industry Testing Station, and 3rd floor of Golden Temple of Donghua Institute of Technology, Yishan Road Headquarters of Shanghai Technical Inspection Bureau, have not been appraised externally. The above four inspection stations were recognized by the state before 1 2. Hold on tight. But 1 is burnt now. (It is recommended to go to the National Light Industry Testing Station) In addition, there are many VVS EF of GIA IGI on the Internet, and the appraisal standards abroad are relatively wide. You can have a look when you die. How can there be so many diamonds of this grade? ~ ~ ~ If there is, regular manufacturers will not buy it and sell it online? GIA is the organization that sets the world diamond 4C standard, and diamonds all over the world firmly refer to his standard. All the domestic colorimetric stones are imported from GIA. GIA is universal, and every diamond has a number. In China, the standard of 1988 GIA is referenced, and the level is relatively tight. For example, the color of GIA certificate we imported is VS/G, and it is estimated to be VS/H in Shanghai. Apart from tariffs, this is also a reason why Hong Kong is cheap. Generally, the price bought in Hong Kong is 20% of the domestic price. If the level is the same ... the highest color in Shanghai is E, GIA can get D, in other words, their D is the E here, which is less than one level (domestic bureaucrats are too conservative). But now many foreign or Hong Kong jewelry companies will send people to get GIA certificates and come back to help their own companies open certificates, so the level is much higher, so this kind of certificate can't be found on GIA website, let alone have a labor manual.
