Carnelian Crystals

About

Carnelian Crystals Carnelian is a translucent variety of chalcedony — a microcrystalline form of quartz (SiO₂) — colored by iron oxide impurities. Its palette runs from pale orange and warm amber to deep reddish-brown, depending on iron concentration and heat exposure during formation. Carnelian sits at 6.5–7 on the Mohs scale and takes an excellent polish, making it one of the most durable colored stones for both display and jewelry. Orange carnelian is the most common form, prized for its warm, saturated tone. Deep red-brown carnelian grades toward sard and is typically darker, denser, and more opaque. The best material comes from Madagascar, Brazil, and India, where it forms in volcanic and sedimentary host rocks. Carnelian has been used in jewelry and seals since at least 4500 BCE — ancient Egyptians, Greeks, and Romans carved it into intaglios and signet rings. Available forms include palm stones, tumbled pieces, spheres, pyramids, freeforms, and mini points. For other warm-toned stones, see our citrine and sunstone collections.
