The French geologist Déodat de Dolomieu probably saw it there in 1784 but took it for black schorl. In 1807 Claude-Hugues Lelièvre described it as a new mineral and called it yenite, after Napoleon's victory at Jena. The name upset German mineralogists, and in 1811 Henrik Steffens renamed it ilvaite, the name used today.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThis specimen comes from the Huanggang iron-tin deposit in Hexigten Banner, Inner Mongolia, China. The deposit has produced unusually thick, lustrous black ilvaite crystals, often with tapered, chisel-shaped tips, sometimes alongside quartz or calcite. It was written up in detail in \u003ci\u003eThe Mineralogical Record\u003c\/i\u003e in 2012.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eIlvaite is a calcium iron silicate built from paired silica groups, with a Mohs hardness of 5.5 to 6. These pieces are dark brown to nearly black prismatic crystals with a sub-metallic to glassy lustre and fine striations along their faces.\u003c\/p\u003e\n\u003cp data-start=\"1100\" data-end=\"1444\"\u003eIlvite is often regarded as a grounding stone, valued for its steady presence and association with endurance. Its dark, earthy tone mirrors the qualities it’s said to inspire—focus, persistence, and stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChemical Composition\u003c\/strong\u003e: CaFe²⁺₂Fe³⁺Si₂O₇O(OH)\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eChakra\u003c\/b\u003e: Root and Solar Plexus\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eSmall\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 35mm x 9mm x 7mm\u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 10g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMedium\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 45mm x 13mm x 8mm\u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 17g\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eLarge\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 50mm x 17mm x 15mm\u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 35g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eX-Large \u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 52mm x 25mm x 20mm\u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 60g\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eXX-Large \u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 60mm x 30mm x 20mm\u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 95g\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e:\u003cstrong\u003e \u003c\/strong\u003e1pc\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cem\u003eWe do our best to buy quality products- although not every rock is the same.
