Very Rare Copper Prehnite Isle Royale Greenstone Turtleback Gem Chlorastrolite

Up for sale is a rare specimen of Isle Royale Greenstone, polished with diamond dust, (following its natural contours as the chlorastrolite crystal formed). Please do look at all photos for quality. These gemstones dance and move in the light. Greenstone specimens are best viewed in bright light.

Collected and polished by myself, owner of "Michigan Gems", a small rock shop in Curran MI, second generation artist specializing in Isle Royale Greenstone and wood sculping. As seen in photos, each of different quality shapes and possible inclusions. Size references and weight in photos. Most measurements are in metric. Please look close, and ask questions if you have any.

I try to use a clear true color lighting, most photographed under 2x or 3x, (sometimes more). The camera used is a Samsung A35 with no filters or edits. Light source, natural white LED 8 inches.

Items in the background are for color reference only. May have irregular surface, healed fracture, and other irregularities. Please see the photos carefully. "Polising Greenstone is akin to opal".

I live in a remote area. Sometimes, small delays may occur.

If that may cause an issue, please contact me. Brought to you by Michigan gems!
