Good specimens of this unusual combination of pyrite on calcite are hard to find. Most have very dull, gray calcite which doesn't look appealing at all. The ones with white calcite on the other hand look amazing! It's incredible how each calcite crystal has a shiny, iridescent, pyrite "clover" in the middle. Condition is surprisingly good considering how many fragile crystals there are. The specimen stands on its own as shown in the photos.
