Before buying a diamond ring, you must write down the necessary budget, and you must have a bottom in your heart. Don't wait until you get to the store, it will only make you lose proper limit. Because the price of diamonds is relatively high, it must be within your own allowable range, and there is no need to make your purse suffer because of comparison.
2. Choose a diamond ring and do the necessary homework
Before buying, it is best to know the relevant information online or from relatives and friends in advance, so that you won't get lost when buying. If your friend has experts in this field, you might as well know more about it. If not, it is recommended to go to Dajindian to consult experts there.
3. Choose diamond rings and shop around.
You must shop around when buying goods such as diamonds, because the styles and crafts of each family are different. There is nothing wrong with observing and learning more. It is also best to buy this kind of goods in high-quality stores, so that after-sales service is more secure.
4. Choose a diamond ring to know which diamond is the most valuable.
Basically, a single diamond is above 1 carat, and the diamonds that have been appraised by professional appraisal institutions such as gia or hrd are the most valuable.
5. Don't forget the requirement of choosing diamond ring "4c"
The 4c we usually refer to refers to the weight, clarity, color and cut of diamonds. Although many people know it, you should ask the shopping guide more in the process of buying, so that the shopping guide will think that you are an expert and will not be too perfunctory to make you suffer.
6. Choose diamond ring cutting technology
The reason why diamonds shine is, to some extent, because of good cutting technology. Therefore, the quality of cutting technology plays a key role in identifying whether a diamond ring is valuable. The ideal cut diamond should be round, with 58 clear cut edges to reflect light to the greatest extent.
7. Choose the perfect color for a diamond ring
The color of a good gem is equally important. Generally speaking, colorless is the best state of a good diamond. With the deepening of yellow, the quality gradually declines. Similarly, customers generally can't tell the color, but merchants will show different quality diamonds for customers to compare.
8. What are the impurities in choosing a diamond ring?
Diamonds contain impurities, and the quality depends on the amount of impurities. Good diamonds have less impurities, but poor diamonds have more impurities.
9. Choose a diamond ring with a written description to ensure the quality.
When you buy a diamond, the merchant should provide a written statement with specific data such as the weight, clarity, color and cut of the diamond you bought, which is also a guarantee for the quality of the diamond you bought.
10. Choose a diamond ring and choose a diamond ring that suits you.
Although there are many kinds of diamond rings in the world now, you should choose the one that suits you according to your age and temperament. Girls under the age of 30 can of course choose fashionable styles, and those over the age of 30 who have certain life experience should try to choose simple and atmospheric styles. Some diamond rings such as small broken diamonds are obviously not suitable for this kind of people.
1 1. Choosing a new style of diamond ring is a coup.
After a while, you may feel that your diamond ring style is out of date, but you don't have to worry about it. Now jewelry stores also have the service of changing styles. It doesn't cost a lot of money to make the original diamond ring look brand-new and become the focus of fashion.
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 said they bought a 2-carat diamond, they put in thistle to avoid rock disaster. Hey? That slack [5]? What is painful and happy? Is this stool steep and patchy? What do you need? The value of a carat diamond is much lower than that of perfect cut's 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 Tory and can only be observed by the watch. Moreover, the gold around the diamond affects the classifier's judgment, which makes it impossible to accurately classify the cut (and leads to inaccurate weight estimation). It can be seen why the grading standard of finished diamonds in the national standard is much looser than that of loose 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.
