Calcite with Duftite
Tsumeb Mine,
Oshikoto Region,
Namibia

Calcite rhombohedral crystals on Duftite from the famous Tsumeb Mine in Namibia. Nice color contrast and in good condition. Original tag says 220, but I'm discounting this to help it find a new home. Comes with earth's treasures tag as well.

Dark green hedenbergite inclusions through the quartz. Nice terminations, and extremely modified points. This locale, probably produces the best examples of this material.

Here's a lot of mostly combo pieces from the Spruce Claim. Tons of these UV react, and are in good condition. These will be removed from the sheet for shipping. Plastic sheet not included as it's too big to ship. There's some scepters and an amethyst as well.
Roughly 3 dollars a crystal.

Fluorite
Greedy Hog Pocket,
Diana Maria Mine, Frosterley,
Weardale, County Durham, England

Here's a Greedy Hog specimen from the nicest flat I've purchased from this mine. Great daylight color change and UV reaction, as well as top luster and clarity in the cubes. I've looked at countless flats of these and not many were comparable.

Grape Agate
(Botryoidal Chalcedony)
West Sulawesi,
Indonesia

Not actually an agate as it's lacking banded layers, these botryiodal amethystine quartz/chalcedony specimens are unique to a small area of Indonesia. Purple being the most common, but can be found in a less common green color as well. This example has larger bots with both colors across the specimen.

Fluorite
50 Year Pocket,
Rogerley Mine, Frosterley,
Weardale, County Durham, England

I just finished reading about the closure of this mine, they have collapsed the entry to prevent claim jumpers from getting in. It will be a long while before they re-access this mine from the Diana Maria side, if at all.
Here's a good example up for grabs!
