It was named for Danbury, Connecticut, the small New England town where the first crystals turned up[1].\n\nThat find was the work of Charles Upham Shepard, an American mineralogist who taught chemistry and spent decades naming new mineral species[2]. He recognised the Danbury crystals as something not yet on the books. He announced danburite as a new species in 1839, a few years after the original 1837 discovery[2].\n\nThe mineral is a calcium borosilicate — a crystal built from calcium, boron, silicon and oxygen[3].\n\nSince that first description, far finer crystals have surfaced elsewhere. The San Luis Potosí region of Mexico yields clear, colourless crystals prized by collectors, and good material also comes from Madagascar, Myanmar and Japan[4].","claude-opus-4-8","1.7.0",{"markdown":590,"model_version":587,"prompt_version":588,"reviewed_at":11},"Danburite has almost no industrial life. What demand it has comes from collectors and, in a smaller way, from the jewellery trade.\n\nAs a gemstone it earns its place on clarity rather than colour. Transparent crystals are faceted into cut stones, helped by good clarity, durability and strong dispersion — the way the stone splits light into flashes of colour[1]. Most material is colourless or white, though pale yellow, straw and brownish stones also turn up[2]. The finest gem-quality crystals come from the San Luis Potosí region of Mexico, with more from Madagascar, Myanmar and Japan[3].\n\nOne thing danburite is not is a source of boron. The crystal does carry boron, locked into a silicate framework[4]. But the mineral is not mined or processed for that boron — the element is drawn instead from borate minerals that release it far more readily. Danburite stays a specimen for the cabinet and a stone for the jeweller, not a feedstock for industry."]
