A gorgeous little 1.0 cm radial spray of glassy stokesite crystals is beautifully perched atop a cluster of pearlescent, parallel-growth cleavelandite blades. This excellent specimen is from the Corrego do Urucum pegmatite of Brazil and is a very uncommon, gemmy spray of the species. Most Urucum stokesites are spherical, radial aggregates.

Although it occurs in other lcoales, in real crystals of interest to the collector, I think this is the only locality that has produced any quantity. Most of those crystals are in radial aggregates that looked as if they were glued together with natural cement, and are not exactly the prettiest of material. However, rarely, specimens like this with more individual, sharply terminated crystals can occur. This specimen must have 100 crystals, to 2mm or so, scattered about in rich veins on the surface of a large shard of schorl tourmaline.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",349,{"id":223,"source_url":224,"license_code":162,"credit_html":225,"title":226,"description":220,"author":166,"original_width":227,"original_height":192},80984,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10169994","Robert M.

This is an aesthetic representation of both species, in unusual association, on a well trimmed matrix of bladed albite so it displays nicely.
