A dramatic, gemmy and wonderful example of Japan-law(90 degree) twinning in quartz - looking like the more common from Peru but 100% this is Bolivian, Ex. Brian Kosnar import. The larger photo shows very clearly the fine twin, and the smaller one emphasizes the superb gemminess of these thin, tabular crystals with their razor-sharp terminations.
