A highly desirable specimen from one of the great, iconic finds of Quartz of all time! Originally discovered in the 1960's by a mineral collector/dealer, these Smoky twins remain one of the most impossible-to-obtain of all American finds. This twin has a brilliant luster, great gemminess, and elegant striations that add interest and brightness. These Smokies are notable for their aesthetics, uncommon habit, and sheer rarity. This pocket of Smoky, Japan Law-twinned Quartz represents the finest American occurrence of both "open" and "closed" twins from the same pocket (this piece shows a closed twin with great chevron twin planes!). Closed twins are more rare, worldwide, than open twins of this habit. The left side is contacted but it displays well anyhow. I have seen only a few of these for sale in last few decades and this is a fine miniature.
