A superb, unusually sharp, 2.5-cm-long pair of Cinnabar PENETRATION twins sitting perfectly on contrasting matrix of Quartz and Dolomite. Seldom do you get such a nice display on one of these twinned crystals, which generally were found in the late 1980s and early 1990s. The adamantine luster is first-rate, and the consistency of color is outstanding. The secondary set of crystals is not as perfectly developed, but nonetheless this is a fine combination piece with a sharp main set of crystals perched against sparkling matrix. Old material from the late 1980s, or early 1990s.
