Big Cubic Zirconia (CZ) 8.33ct Big finely colored Cubic Zirconia gemstone, Tourmaline imitation. CZ is always synthetic, it does not occur in nature. Cubic Zirconia is often used as an imitation of other, more valuable gemstones, for example Diamond, Sapphire and Ruby, Tanzanite and Zircon. But CZ is a fine gem in its own right, on its own merits. CZ is a remarkably heavy mineral, the specific gravity is about 6, which makes it clearly heavier than all common gemstones. CZ is also very transparent, i.e. "clear", and has a strong "fire", i.e. a flash of different colors created by the dispersion of light, which can be seen especially in colorless and lighter stones as a strong flicker of colors when turning the stone. And CZ is too.
