This beautiful mineral was recently sold for a whopping $5,000 by Rob Lavinsky of the Arkenstone. Measuring 9 x 7 x 6 centimeters, the stunning specimen is described as Chalcedony on Chrysocolla stalactites (pocket). With a blue-green chalcedony-crusted exterior, an unusual pocket that opens to reveal the highly textured interior, and assorted quartz-covered chrysocolla stalactites the color of icy glaciers, the mineral is truly a unique sight to behold.
The piece, obtained by miner Frank Valenzuela in the 1960s, is described as "a classic example of the quartz-covered chrysocolla stalactites from that time, but unusual in that it was preserved as a whole pocket." Thanks to the partially translucent exterior and a small hole in the back, the entire mineral glows when backlit, making it an even more phenomenal choice for display.
