Cold Mountain Thundereggs - Barrel Lot
Cold Mountain Thundereggs are similar to Butterfly Jasper, but offer a brighter range of colors. They can contain water banding, and feature red, mauve, or black "webbing." While technically a rhyolite due to its thunderegg nature, Cold Mountain Thundereggs are highly silicate and filled with brecciation. This material takes an exceptional polish, which makes it ideal for both cabochons and specimens. The rough nodules usually have a bumpy exterior, but occasionally can be smooth. Nodule sizes have a large range, around 2 inches to 8 inches.
This is for one barrel lot of rough rock, uncut Cold Mountain Thunderegg nodules. One barrel is approximately 500lbs of rock, shapes and sizes will vary throughout the lot.
The second image shows an example of the nodules wet, and the last three images show examples of cut and polished Cold Mountain Thunderegg specimens.
