Peridot is a gem-quality variety of the mineral olivine, known for its distinct bright green color, ranging from yellowish-green to olive-green. It forms in igneous rocks, particularly in volcanic areas, and is one of the few gemstones that comes in a single color. The vibrant green hue of peridot is due to the presence of iron in its crystal structure.
Peridot is one of the birthstones for the month of August and is often associated with positive energy, protection, and healing. The stone is believed to bring good luck, dispel negativity, and promote a sense of well-being. It has been used in jewelry for centuries, often set in rings, necklaces, and earrings.
