I have to say up front that this piece simply is better than the photos indicate. The HIGH luster of the faces made it difficult to photograph. The specimen is in great shape overa ll, and the robust crystals with their sharp, well-defined surfaces are very hard to find from this mine. The piece is twinned and shows the classic "cogwheel" shape that was made famous by the classic specimens from Cornwall, England. Great quality on the display side, and the only point of contact is on the back/bottom where it detached from the pocket wall. Specimen # BOL711B19 Show more
