 | "A large, deep red, SCEPTERED(!) crystal of Cinnabar, dramatically isolated on a matrix of quartz and dolomite. The crystal measures 1.5 cm, rising well above the matrix, and is complete and exposed all around. A smaller crystal is nearby. Cinnabar is a colorful mineral that adds a unique color to the mineral color palette. Its cinnamon to scarlet red color can be very attractive. Well shaped crystals are uncommon and the twinned crystals are considered classics among collectors. The twinning in cinnabar is distinctive and forms a penetration twin that is ridged with six ridges surrounding the point of a pryamid. It could be thought of as two scalahedral crystals grown together with one crystal going the opposite way of the other crystal. Cinnabar was mined by the Roman Empire for its mercury content and it has been the main ore of mercury throughout the centuries. Some mines used by the Romans are still being mined today. Cinnabar shares the same symmetry class with quartz but the two form different crystal habits." Location: Tongren, Guizhou, China Size: 9 x 5.5 x 3.5 cm. Weight: 2.0 lbs.
