At first glance, observe its luster.
When we look at a blue diamond with the naked eye, we must first look at its gloss. Diamonds themselves have a particularly strong luster and become very dazzling in the sun. This actually means that the dispersion value of the diamond is obvious, and the colorful fire phenomenon can be seen on the side of the diamond. There is also a kind of diamond, which has strong thermal conductivity. At this time, breathing through the mouth will form a layer of fog on the surface of the diamond, which will soon disperse. But oil droplets are different on it. When oil drops are on it, a layer of oil will be formed on its surface. This method is also an important method to identify the true and false blue diamonds.
Colored diamond such as blue diamond is very rare in nature.
Most diamonds in nature are colorless and transparent, so blue diamonds are rare and naturally expensive. Even if the color is slightly yellow, the price of yellow diamonds with a lot of stocks is higher than that of colorless and transparent diamonds. However, many blue diamonds on the market have changed color. These diamonds are mainly turned blue by blue light. Such blue diamonds are purely artificial, and these blue diamonds are worthless.
At present, a lot of blue diamond jewelry on the market appears in some large-scale jewelry auctions, and there are not many opportunities to see it in normal jewelry stores, mainly because of its high value, and few people buy it in jewelry stores.
There are so many ways to distinguish between true and false blue diamonds, as mentioned in the article above. In fact, no matter what color the diamond is, the identification method is similar. It is a good thing to learn these identification methods and know whether the diamonds you buy are true or not.
