I bought a few 925 silver bezel settings at the May 2025 rock and gem show. I knew right away when I looked at them which stones would look great in it, and Nuummite was one of them!
This stone originates from Greenland and I bought straight from the miner who hand harvests from the land. Nuummite is a trade name for an Anthophyllite-Gedrite series of stones that contain a certain iridescence. It is quite rare, as one can only get to the locale via boat during certain months when the ice has melted. It can be seen in a variety of 'grades', the highest seemingly being the ones with the most colours and flash. Also known as The Sorcerer's Stone, this stone is said to be around 3 billion years old! Some people are selling Coppernite, Larvikite, and Arfvedsonite as Nuummite so watch out! Though they may look similar, they have a completely different chemical composition. I enjoy using mindat.org (a mineral database) for comparing crystals to see how similar they are. I hope that helps you with your crystal adventure!
