Peridot is a vibrant gemstone celebrated for its refreshing olive-green to yellowish-green hues, symbolizing prosperity and good fortune. Composed of the mineral olivine, peridot’s vivid color is due to the presence of iron within its crystal structure. It is one of the few gemstones that occur in only one color, though the intensity and tint can vary depending on the amount of iron. Often associated with light and warmth, peridot has been cherished since ancient times, notably by the Egyptians who called it the “gem of the sun.” Its lively, summery glow makes it a popular choice for jewelry, evoking feelings of renewal and vitality.
