The termination is accented be small gem phenakites at its tip, and behind like bracing struts. The aesthetics are striking, and the contrast of white on dark makes the piece MUCH more appealing to my eye than the rest of these specimens I saw, which are generally white phenakite on white matrix. This exceptional miniature was cherrypicked by a European friend travelling in Burma, who has obtained and exported much of this material over the years.

It comes from the Greek *phenax* — deceiver — because the colourless, glassy crystals were so easily mistaken for quartz[1].\n\nThat confusion is what earned it a name. In 1833 the Finnish-born mineralogist Nils Gustaf Nordenskiöld recognised the crystals as a distinct species[2]. He named them for the trick they had been playing on collectors. His material came from the emerald and chrysoberyl mine on the Takovaya stream, near Yekaterinburg in the Urals of Russia[3]. There the large crystals sit embedded in mica-schist — a flaky, layered rock.\n\nAn older spelling, **phenacite**, appears in past writing, but phenakite is the accepted form today[4].\n\nSome of the largest crystals ever recorded came not from Russia but from Greenwood in Maine, where examples measuring 12 inches across and weighing 28 pounds have been found[5].","claude-opus-4-8","1.7.0",{"markdown":632,"model_version":629,"prompt_version":630,"reviewed_at":11},"Phenakite has almost no industrial life. It is a beryllium mineral, but it occurs too sparsely and too scattered to be worth mining for that metal — beryllium comes from other ores. What demand exists comes from gem cutters and collectors.\n\nCut and polished, it makes a quietly impressive gemstone. Its refractive index — the measure of how strongly it bends light — runs higher than that of quartz, beryl or topaz. A faceted phenakite is consequently rather brilliant, and may sometimes be mistaken for diamond[1]. For gem purposes the stone is cut in the brilliant form, the same many-faceted shape used for diamonds[2].\n\nIt is also hard enough to resist most everyday scratches, which helps it survive as a wearable stone. Even so, faceted phenakite stays a rarity, prized by gemstone collectors far more than it is set in jewellery for sale."]
