This listing is for one Peridot Pear Cut Gemstone, each Gem averages 0.4cts each.
Peridot is the gem quality version of a silicate mineral known as Olivine. Peridot is also one of the few gemstones that occur in only one color, an olive green. The intensity and tint of the green, however, depends on how much iron is contained in the crystal structure, so the color of individual peridot gems can vary from yellowâ€”to oliveâ€”to brownish-green. The most valued color is a dark olive-green.
Olivine in general is a very abundant mineral, but gem quality peridot is rather rare. This is due to the mineral's chemical instability on the Earth's surface. Olivine is usually found as small grains, and tends to exist in a heavily weathered state, unsuitable for decorative use.
