Colección: Dumortierite Collection

Shop natural dumortierite gemstones and cabochons for jewelry making and collecting. Our dumortierite collection features deep royal blue to violet-blue dumortierite in quartz cabochons, raw dumortierite crystals, polished spheres, and tumbled stones sourced from Brazil, Madagascar, Namibia, France, and the United States. Dumortierite is a boron aluminum silicate mineral prized for its striking intense blue color — one of the deepest and most saturated natural blues found in any opaque gemstone. It most commonly occurs as inclusions within quartz (dumortierite quartz), creating a beautiful blue-and-white patterned material ideal for lapidary work. Named after French paleontologist Eugène Dumortier. With a Mohs hardness of 7 (as dumortierite quartz), it is durable and well suited for cabochons, pendants, and earrings. Ethically sourced with full origin disclosure.
