Sapphire is just as valuable as ruby. When it comes to quality, the price can be extremely high if the color, clarity, and cut are excellent. Even a small sapphire can cost tens of thousands of yuan. Unfortunately, there are many fake sapphires on the market, so buyers should be cautious. If you see a sapphire being sold for a very low price, it's likely to be a counterfeit.
As a type of jewelry, sapphire is popular among collectors. With the growing interest in collecting, it's essential to understand how to identify real sapphires from fakes. This knowledge helps avoid being deceived during purchases and sales.
The most common fake sapphire found in the market is glass. Identifying glass sapphire is not too difficult. When glass is formed at high temperatures, it shrinks naturally when cooled, creating a slight indentation on the surface. This feature is hard to spot with the naked eye but becomes visible under a magnifying glass. When examining with a 10x loupe, you should look at the stone from an angle rather than straight on. This technique makes it easier to detect concave areas, which are typical of glass. Also, glass often contains bubbles, while natural gemstones do not. These bubbles can be spotted using a 10x magnifier.
Another type of fake is synthetic sapphire. To distinguish between natural and synthetic, start by looking at the internal structure. Natural sapphires have a random, chaotic crystal pattern, while synthetic ones tend to have a more uniform and ordered structure. Synthetic sapphires are often too clean and flawless, which is unusual for natural stones. Real sapphires usually have some imperfections or inclusions. Additionally, synthetic stones may appear overly bright and lack the depth of natural color. In contrast, natural sapphires have a more subtle brilliance that radiates from within, showing higher purity and a more natural appearance. (Li Feng)
