Artificial stones are difficult to distinguish from real ones without special equipment. This is used by scammers, posing as an imitation gem. For example, the streets of Bogota, the "emerald capital" of Colombia, are full of merchants selling artificial emeralds, which even a knowledgeable amateur is unlikely to distinguish from real ones. When people come to Colombia, Brazil, or Thailand, they think they sell exclusively natural stones on the street since mining is happening here.
When buying precious stones, the following frauds are possible:
1) incorrect representation of weight;
2) color change and its incorrect evaluation;
3) concealment of defects and incorrect assessment of cleanliness;
4) forgery, the presence of corrections in the expert opinion or in the certificate.
It is always necessary to approach the seller's recommendation to take the stone to a familiar appraiser with caution. It happens that sellers and appraisers are in collaboration with each other. Therefore, duplicate the information you receive through other channels. If you buy an expensive piece of jewelry, do not be lazy to come to the store to purchase with a qualified expert. The cost of such a service is, on average, about $ 100. but this will significantly reduce the risk, and in some cases, you can even get a discount on the purchase. The real permissible deal on jewelry is from 10 to 20%.
Sometimes gems are described better than they actually are. The purity and color class is often overestimated. The prices seem more attractive than those of other sellers. In fact, in other stores, prices for stones of comparable quality are sometimes more profitable.
To ensure that the certificate was issued for this particular stone. The first thing to do is compare the weight in carats and the size stone with those indicated in the certificate. Unfortunately, suppose the stone is in the frame. The certificate may be excellent in some cases, but the stone is substituted. In that case, it may turn out that it is impossible to remove the exact dimensions for comparison.
Issuing expert opinions on non-existent laboratories and research centers are becoming an increasingly common problem.
There are cases when the information in the certificates for precious stones is changed. For example, the purity class and color are corrected. Suppose you have any questions about the expert opinion or certificate information. In that case, it is recommended to call the laboratory and provide the number of the certificate or expert opinion to find out the correctness of the information contained in it. Never trust expert opinions and certifications that are attached to the jewelry. There is a practice of correcting data on the weight of the insert (instead of 0.01, write 0.10 carats). Or the characteristics of a gemstone (for example, in the attributes of a VS1 diamond.
An extra letter is added, and VVS 1 is obtained, and such a stone weighing one carat costs 5 thousand dollars cheaper). Sometimes even a completely different certificate from a product that already has been sold is attached to the decoration. Therefore, if possible, check the stone's authenticity with gemological equipment and specify its characteristics. If you are not given something to double-check, it is better to refuse a dubious transaction.
The distortion of information is not the retailer's fault but in the process of its transmission. Sometimes the accompanying documents and labels on the jewelry initially contain an error. This may happen due to the simple illiteracy of the manufacturer or the wholesaler, as imported stones are often used in modern jewelry. Some countries can sell either a fake stone or a stone with reduced quality characteristics with great pleasure. At the same time, a beautiful package or a luxury store where you came to buy will not protect you from further disappointment.
If you see that the words of a jewelry seller during a responsible conversation may have several meanings, do not be lazy to clarify what exactly he means. Especially carefully review the certificates and their compliance with the decoration labels.
During a responsible conversation, do not waste attention only on words. Analyze the nonverbal signals of the interlocutor: eye movements, gestures, facial expressions, poses. They will tell you when you are being told a lie.
Learn to distinguish between roles and the people who play them. Do not be deceived by the seller's solid appearance and thoughtful voice in a prestigious store. Try to learn as much as possible about the manufacturer, about the store's history, before making a serious purchase. This is especially true for products with large natural precious stones (sapphires, rubies, emeralds).
How this decoration suits you or what a prestigious thing it is), do not rush to make a decision. If everyone around you is forcing their opinion on you in a chorus, different from yours. Maybe they are just figureheads. If you are persistently persuaded to buy something urgently, ask yourself if you can do without it.
