The first specimens turned up in 1967 near the Owyhee Dam, in Malheur County, Oregon, and three American researchers — Lloyd W. Staples, Howard T. Evans Jr., and James R. Lindsay — described it as a species new to science[2]. The same Oregon work turned up a near-twin, pentagonite. The two are dimorphous: identical in chemistry but built into two different crystal shapes, like the same bricks stacked two ways[3].\n\nFor its first decades cavansite was a rarity known mainly from that Oregon ground. Then the basalt quarries around Pune, in western India, began yielding it in quantity. These quarries cut into the Deccan Traps. That name covers vast stacked sheets of ancient volcanic basalt that blanket much of west-central India. The mineral grew best inside the cavities left by old gas bubbles in that rock[4]. Specimens from the Wagholi quarries near Pune carry deep, almost electric blue crystals. They are now the ones most collectors picture when they hear the name[4][5].","claude-opus-4-8","1.7.0",{"markdown":547,"model_version":544,"prompt_version":545,"reviewed_at":11},"Cavansite earns its keep on a shelf, not in a factory. The mineral carries vanadium, a metal industry does want, so in principle it could be an ore source for it. In practice it is not treated as one. It is too scarce and too scattered to mine for the metal, and is not generally considered an ore mineral[1].\n\nWhat it does have is colour. Its rich, bright blue crystals, often gathered into small rounded sprays, make it a sought-after collector's mineral — prized for display rather than for any material it yields[1][2]."]
