One set of twins is nice, two is pretty rare, but three is amazing, especially when it is the dramatic appeal you find in a large thumb! Three sets of Japan Law twins set in one tight cluster. The quartz crystals are frosted to gemmy, with an equally frosted to glassy luster. Fortunately, there are only a few dings, but they do little to detract from the specimen. Even better in person. Rare to find these so small, that a thumb can be taken out...
