This effect can be reversed by giving the stones a second Zircon is also prone to cracking and chipping if banged too hard. For this reason, care must also be taken when Zircon gemstones. Another important factor when faceting Zircon is to minimize the appearance of its strong by cutting along proper angles.

Zircon is sometimes confused with Cubic Zirconia. Cubic Zirconia, a synthetic, inexpensive Diamond simulant, resembles colorless Zircon and has a similar sounding name.
