jewelry wholesale guangzhou Common types of fake diamonds (на)

Опубликовано в от Король

Diamonds are noble and luxurious ornaments, and jewelry with natural diamonds is the crown of jewelry. Однако, diamonds are scarce and expensive, especially the larger ones, and most people don’t dare to care about them. Как результат, the use of cheap gemstones, man-made gemstones and even glass to replace or pretend to be diamonds intensified secretly or publicly, and the business of fake diamonds is also booming. According to the research and statistics of Mr. Wang Shu, there are 13 kinds of common fake diamonds of all kinds, и 7 kinds are introduced as follows:

(1) Glass: Fake diamonds made of glass are easy to distinguish because of their low refractive index and no flashing colored light like real diamonds. People with a little experience will know at a glance. Кроме того, a white porcelain bowl can be used to hold a bowl of clear water. The colorless glass products that pretend to be diamonds are immersed in the water and the outlines cannot be seen, while the dark outlines of real diamonds appear very clear in the water.

(2) Artificial spinel: The difference between it and diamond is that it lacks the flickering color light. If it is immersed in diiodomethane, the outline will be blurred, while the outline of real diamond is very clear.

(3) Crystal and Topaz: The transparent crystals of these two natural minerals look a bit like diamonds after being polished, but they lack the sparkling color light. And they are all “heterogeneous bodies”, while diamonds are “homogeneous bodies”, which can be easily distinguished with a polarizer.

(4) Zircon: Before the emergence of man-made cubic zirconia, zircon was the best diamond substitute. Zircon has a strong birefringence, то есть, it has two refractive indexes, and the difference between the two refractive indexes is relatively large, resulting in a very special optical phenomenon. When using a magnifying glass to observe the polished zirconium In the case of a stone faceted gem, it can be seen from the top face that the bottom face and the ridgeline have obvious double shadows. And because diamond is a “homogeneous body”, there is no double shadow phenomenon.
