Sapo Mine blue caps were one of the most stunning new finds of the late 1990s, and now are sought after and hard to get. When they came out, although there were many small crystals per se, there were not many fine thumbnails in the sense of a sophisticated taste wanting a "thumbnail sized exquisite piece," but not just a broken-off single stump. THIS cluster is the best thumbnail I can recall seeing from the finds. It was in the collection of Jim and Dawn Minette, and then sold to thumbnail collector Jim Houran 2 years ago. It features a 2.5-cm-long doubly terminated crystal with intense color, just perched up on a natural stick in midair.
