As a natural gemstone, zircon is a natural product in nature, with a hardness of 6-7.5, which is equivalent to many popular gemstones. The luster is from diamond luster to glass luster. The dispersion value is 0.038, which puts many gems underfoot, so strong dispersion is a highlight of zircon. The cut zircon looks full of fire, even not inferior to the brilliance of diamonds.

According to the degree of crystallinity, zircon is divided into three types: high, medium and low. The good crystallinity is called high type, and the one with poor crystallinity close to the amorphous state is called low type. We can distinguish between radioactive and non-radioactive zircon by appearance. Generally speaking, the clean interior, blue, golden yellow, colorless, and reddish brown are high-type zircons, which are basically non-radiating.
