Peridot

Carat weight significantly impacts value at higher quality levels. Peridot is common in small sizes, but fine-color, clean stones above 5 carats are less abundant, and gems over 10 carats in top quality are rarer and command higher per-carat prices.

Color is the principal value factor. The most prized peridot exhibits a vivid, saturated medium green with minimal brown or yellow, often described as 'lime' or 'apple' green. Stones that are too yellowish, brownish or dark are less valuable. Color is influenced by iron content and can vary by deposit.

Peridot commonly contains reflective 'lily pad' inclusions and other internal features. Eye-clean stones with good transparency are valued more highly, especially in larger sizes. Heavy inclusions or fractures reduce brightness and durability.

Cut quality is important to maximize brilliance and even color. Well-proportioned mixed cuts reduce windowing and dark areas, showcasing peridot's natural sparkle. Improper cutting can leave stones with dull centers or overly dark corners that detract from appearance.

Peridot deposits occur in volcanic and mantle-derived rocks in many countries, including China, Pakistan, Myanmar, the United States (Arizona), Vietnam and others. Chinese and Pakistani sources have provided significant amounts of fine-quality material, including larger gems.

Demand is driven by its bright, summery color and birthstone status (August). Peridot is widely used in silver and gold jewelry at accessible price points, with occasional high-end pieces featuring exceptional stones.
