As with the other specimens of this style, all the crystals seem to be about 6-8mm in size. But there are so MANY of them here, it is a gorgeous specimen for any species, and even with as many olmiite as has been found of late, this is a radically different style and appearance. It looks for all the world like a Tsumeb cobaltian smithsonite specimen of top quality - and quite unlike previous finds of olmiite , with these unusual, flattenned, squarish crystals.

It is a very aesthetic specimen nearly 4 inches across, with remarkable contrast between the sharp and symmetric olmiites, and the rolling matrix underneath (sparkling little calcites dusted with white oyelite). This piece is very 3-dimensional, with elegant olmiite crystals climbing up one side like hikers on a mountain. The crystals have high lustre, great translucency, and a very unique overall aspect compared to other mineral specimens. It looks for all the world like a Tsumeb cobaltian smithsonite specimen of top quality - and quite unlike previous finds of olmiite , with these unusual, flattenned, squarish crystals. I saw the majority of this pocket laid out in front of me, and this is one of the very few (under a dozen) large and fine specimens of this style that were found.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",1000,813,{"id":312,"source_url":313,"license_code":114,"credit_html":314,"title":315,"description":316,"author":118,"original_width":185,"original_height":317},71379,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10140304","Robert M.

The layered hematite matrix gives the complimentary, ultra-sparkly, water-clear calcite crystal coating a distinct lavender tint. Many of the calcite crystals are doubly terminated. Olmiite is the manganese-dominant variant of poldervaartite and is found only at the N’Chwaning II Mine, its type locality now.
