Here are some pictures of the Calcite finds that Dave and I found this last weekend in southeast Colorado.
Unknown mineral found in a Calcite vein. It it very fragile and made of tiny red cubes. Our best guess is Hematite after Pyrite. -------------------- |

Awesome finds! I have a few pieces like the white one but not the little cubes. There are pretty clean so looks like just soap and water will do nicely but if you needed to clean them more would you use SIO for any of that? Some of them have that pyrite/hematite and that could get damaged with SIO and you cannot use acid since it will eat the Calcite, right? What do you do for more vigorous cleaning to make em look really nice?

Soapy water, textile gun or ultrasonic cleaners seem to be effective. -------------------- |
