The scolecite crystals get up to 6 cm in length and are colorless and lustrous. The few unterminated scolecite crystals do not affect the overall quality of the specimen. It is amazing to see such a perch for the powellite, and it really enhances the overall aesthetics of the powellite crystal to be in such a \"nest\"\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",400,352,{"id":464,"source_url":465,"license_code":275,"credit_html":466,"title":467,"description":468,"author":469,"original_width":470,"original_height":471},14054,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=132806237","Eric Polk, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=132806237\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Scolecite with laumontite NHMLA.png","Sample of scolecite with laumontite collected from Nasik, Maharashtra, India.

The fibre curls and writhes as it loses its water, and that wriggle gave the mineral its name. It comes from the Greek *skōlēx* — worm — chosen for that reaction to the blowpipe, the hot flame early mineralogists used to test a sample[1].\n\nThe mineral was described in 1813[2]. It was placed in the zeolite group, a family of minerals built from a rigid framework of silicon, aluminium and oxygen with water trapped in the open spaces inside[3]. Within that family scolecite sits closest to natrolite, another slender, needle-like zeolite[4].\n\nMost of its human story since then has been a collector's story rather than an industrial one. The finest specimens come from the Tertiary Deccan Basalt near Nasik and Pune, in the Indian state of Maharashtra, where scolecite forms the radiating white sprays of fine needles that fill museum cases[5]. Good crystals also turn up at Berufjörður, near Djúpivogur in eastern Iceland, and in Scotland, California and Brazil[5].","claude-opus-4-8","1.7.0",{"markdown":638,"model_version":635,"prompt_version":636,"reviewed_at":11},"Scolecite has no real industrial job. The zeolite group it belongs to does heavy lifting in industry — as adsorbents that soak up water and gases, and as catalysts that speed chemical reactions — but those tasks are handed to synthetic zeolites made to order, not to this natural mineral[1].\n\nWhat scolecite is prized for instead is its appearance. It grows in radiating sprays of fine white to colourless needles, and the best of them — from the Deccan Basalt of Maharashtra, India — are sought by collectors and shown in museum cases as display specimens[2]."]
