Formal jewelry sales should be accompanied by an appraisal certificate to clarify the quality of jewelry and ensure consumers' right to know. Therefore, consumers must not forget to ask for an appraisal certificate when buying jewelry, and carefully check whether the corresponding contents of the product label and certificate are consistent, especially the number and photo.
What should I do if I am worried about buying fake diamonds?
Many friends buy diamonds for the first time and are afraid of buying fake diamonds. In fact, as long as they pay attention to three factors, they don't have to worry:
1, to judge whether the merchant really deals in jewelry. Because the reputation of this industry is very important, if selling fake goods will be uniformly isolated, it will not be worth the loss, and there will generally be no fake goods. But be careful of two kinds of stores: one is a tourist attraction store, and the other is a women's clothing store that mainly deals in various trinkets. If both shops claim to have real diamonds and real jadeite, be careful!
Don't worry about buying synthetic diamonds. I can tell you for sure here: don't worry, synthetic diamonds can't be bought! Because synthetic diamonds are more expensive than natural diamonds. The artificial diamond mentioned here only refers to the components with the same molecular morphology. If it is to be polished into 57 or 58 standard surfaces, the cost will be higher. Synthetic diamonds were first developed by Japan in 1955, but they were not mass-produced. Synthetic diamonds are rare in the market because they are more expensive than natural diamonds.
3. Don't worry about buying cheap gems such as counterfeit diamonds, such as colorless gems, colorless spinel, zircon, strontium thorium, yttrium aluminum matte, yttrium gallium garnet, etc. Solving this problem is actually very simple: trust our appraisal agency! As long as you can produce the appraisal certificate of an appraisal institution with certain qualifications, we think there is generally no need to worry.
Scientific maintenance of diamonds
1, the diamond ornaments should be stored separately. Don't put it together with other ornaments, so as not to damage the essence of diamonds by friction or oxidation. It's best to buy more small boxes with diamond ornaments for separate collection.
2. Never wear diamond ornaments after wearing perfume. Because diamond has oil absorption, grease or dust will stick to the surface of diamond and make it dull. It is suggested that you can soak in alkaline detergent with water for 1-3 minutes, and then rinse with clean water.
3. When wearing sweaters or knitted clothes, try to pay attention to whether the diamond ornaments worn on your body have been torn off. After all, diamonds are not cheap.
Cleanliness of diamonds
Diamonds, like other things, can be dyed, dyed or dyed by dust. All kinds of solvents, powders, soaps and even oils produced by human body will form films on the surface of diamonds, which will reduce the luster of diamonds. In addition, air may also oxidize or discolor jewelry. Here are some recommended diamond cleaning methods:
1, rinse with detergent
First pour a little detergent into the bowl, stir with warm water to foam, then put the diamond into the bowl and rub it gently with a soft brush. After brushing, take it out and put it into a metal net or filter tea set, rinse it with warm water and dry it with a soft cloth.
Step 2 soak in cold water
Dissolve the detergent in cold water at the ratio of 1∶4, and soak the diamond ring in the solution for several minutes. After taking it out, gently wipe it with a soft brush, rinse it with solution again, and then dry it with a paper towel.
3, cold water immersion method
Add the same amount of water to half a cup of household ammonia water, immerse the diamond in the solution, stir it gently, and then use paper to absorb the water.
In addition, the use of ultrasonic cleaners and other special jewelry cleaners is also effective.
