The imitations circulating on the Web are getting better and
even if we think that we would never get caught up, the truth is that it happens and more and more frequently. When it comes to identifying a fake, it is always advisable to go to an expert, we give you some guidelines to have a first contact with the jewel: - In the first place, it is fundamental to have confidence in the person who sells, who has a store facing the public and who has been on the market for a long time, David Durán, an expert in gemology at Auctions Duran, recommends. - We should never trust a certificate issued by the store. A diamond should always accompany the certificate of an independent and objective gemological laboratory, says Durán. - To make a precise assessment we will need a magnifying glass of 10 magnifications, only this way we will be able to appreciate the inclusions (imperfections) and determine the degree of purity of a precious stone. Keep in mind that 99% of the stones are treated and there is almost no absolute purity. - The main difference between a diamond and a zircon is that the diamond is never transparent, says the Valladolid jeweler Secundino González. The diamond returns approximately 70% of the light it receives due to the imperfections or carbons that hinder its exit, this makes it have a different brightness. - It is very unlikely that an emerald is clean like the glass of a bottle because of these imperfections. - Regarding weight, one carat is equivalent to 200 milligrams. - Gold and silver must carry two maracas, one from the manufacturer and another from the contrast laboratory. Gold is marked with a number, the 750, which means that it has 750 parts of pure gold and the rest is alloy (18 carat or gold), that is, what gives it hardness and color. In this way, the purity of 999.99 thousandth will be softer (24 carats). Keep in mind that this measure is not the same for all countries. - The authentic pearls are formed by several nacre, then have a series of roughness. Hence the fact that many people try to put a tooth to recognize them .. - Unlike fake pearls, good ones reflect light from the inside, and also, being an organic jewel, like coral, when we touch it, it takes the temperature of our body.
