Peridot Trillion Faceted Stones, AA-Grade


The clarity and appealing green color makes peridot one of the most popular stones for use in all kinds of jewelry. Use this trillion-cut faceted peridot on its own for a simple ring, or set it alongside gems of complementary colors in more complex designs—it looks great set in any metal color. Peridot is one of the birthstones for August.

Peridot is the gem form of the mineral olivine. It is one of the few gemstones that occur in only one color; the green hues can vary from yellowish to brownish green, from light olive green to vibrant green. The color of each stone is a result of iron in its chemical composition. Rio Grande sources the highest-quality peridot stones available, avoiding those with visible black inclusions.

The trillion cut features three curved sides, rounded corners and brilliant faceting.
