Quartz
An amazing Japan-Law twin quartz specimen with a wing-span of over 10 centimeters! Behind the twin is a cluster of conventional quartz crystals that serves as a natural base, so that this specimen stands up perfectly all on its own. The twin is wonderfully transparent, too, which is NOT the case with many of these. The twin has pretty bevels around its edges; on one side there is a ripply area that was where the twin grew against something, then later rehealed and formed little faces once the contacted material etched away (or the twin broke away). You can see this same phenomenon along one of the sides. This is just a spectacular example of the rarest form of quartz twinning, much desired by collectors and very seldom seen in specimens of this magnitude. From the collection of Ed Ruggiero. 10.4 x 9.6 x 5.3 cm
