Aventurine Collection

Shop natural aventurine gemstones and cabochons for jewelry making and collecting. Our aventurine collection features green aventurine, blue aventurine, red aventurine, and peach aventurine in a range of forms — including polished cabochons, tumbled stones, spheres, and palm stones sourced from India, Brazil, Russia, and Tanzania. Aventurine is a variety of quartz characterized by its sparkling aventurescence — a glittering optical effect caused by tiny reflective mineral inclusions (fuchsite mica in green aventurine, hematite or goethite in red and peach varieties, dumortierite in blue). Green aventurine is the most common and popular form. With a Mohs hardness of 7, aventurine is durable and well suited for cabochons, beads, pendants, and ring stones. Ethically sourced with full origin disclosure.
