White, white, colorless type

Colorless, white, and white-based gemstones emit a beauty that is different from colored gemstones. Colorless diamonds, rock crystals, white topaz, moonstones, and pearls are well-known, but there are also many other attractive gemstones such as white sapphire, goshenite, and acroite. Depending on the type of gemstone, there are some gemstones that are rarer if they are not colored.
