Peridot is one of the few gemstones that occur in only one color: basically 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 yellow-green through olive green to brownish green. The most valuable is considered a dark-olive green color.
Good quality peridot in large sizes is rare. Peridot from laboratory grown crystals have the same chemical composition, hardness, and other basic physical properties as the corresponding natural gemstones, but are cleaner, more perfect stones.
Most of the larger peridot jewellery found at Tiare Black Pearl (as in the above samples) are laboratory grown.
