Dioptase, Plancheite after Calcite Dioptase, Plancheite after Calcite Dioptase, Plancheite after Calcite

Rare old specimen of Dioptase and Plancheite replacing scalenohedral Calcite crystals. The crystals reach 1.3cm in length. These are from a small find found way back in the 1920s. The Mineralogical Record has an article on these specimens in the November-December 2005 issue. According to the article, the Calcites were first replaced by the Dioptase with are in turn partially replaced by Plancheite. Ex. Kent England collection and very rare to find for sale.

Unusually etched, gemmy yellow Heliodor crystal with sharp, parallel ridges giving it a ribbed effect unlike any I've seen before. A floater with each termination relatively flat and etched. This style of etching is very uncommon and much different than the etched Ukranian Heliodors.

Transparent Fluorite crystals of two habits (cubes and cubes with bevelled edges) on Galena with black Sphalerite. A druse of white Calcite crystals coat the top. Much better in person as the Fluorites appear like ice cubes attached to the Galena.

Manganoan Adamite Manganoan Adamite Manganoan Adamite Manganoan Adamite

Cluster of lustrous Adamite crystals with typical chisel-shaped terminations in a spray formation in a limonite vug. This is old material from the 1980s with the rare and desirable purple coloration. Largest crystals reach nearly 2cm long and over 5mm across at the terminations. These can sell for ridiculously high prices due to their rarity and I consider this one a bargain.
