Gem-grade zircon is very similar to diamond after cutting. It is a natural gem with high dispersion value. The colorless and transparent zircon resembles diamond and is a good substitute for diamond.
Swarovski zirconium refers to "zircon".
Zircon, also known as zircon, is called "hyacinthus orientalis" in Japan. It is a silicate mineral with the chemical formula ZrSiO_. It is the main ore for refining zirconium metal, and contains impurities such as Hf, Th, U and TR.
Zircon widely exists in acidic igneous rocks, metamorphic rocks and other sediments. The chemical properties of zircon are very stable, so gem-grade zircon can also be seen in river gravel. There are many kinds of zircon, and different zircon will have different colors, such as black, white, orange, brown, green or colorless and transparent. The cut gem-grade zircon looks like a diamond. Zircon used to be called zircon.
