A classic, impressive, large Japan-law twinned quartz twin regally commands this very showy and excellent large specimen from the well-known PC Mine of Montana. The textbook, sharp, tabular, transparent to translucent twin is 7.2 cm across with satin luster faces and classic, razor-sharp chisel terminations. The sculptural, large 360-degree plate hosts 5 more smaller Japan-law twins, as a significant bonus, among the ordinary tabular quartz crystals. The noted periphery wear certainly has only minimal impact to the overall very high quality of this specimen. The mine is famous for its Japan-law quartz twins. Specimens of this quality came out in the 1980s and 1990s, with very few since. Self-collected by well-known Northwest and Washington field collector, Karl Faddis. He had a superb collection of self-collected material. We obtained his collection in 2011. An outstanding large example of the open Japan-law twin quartz style on large matrix from the mine.
