β“˜ Volkovskite
Formula: KCa4[B5O8OH]4[B(OH)3]2Cl · 4H2O
Description: Volkovskite here is composed of intergrown bladed crystals of glassy and gemmy, nearly colorless , crystals reaching 2.5 cm in length. They are emplaced on a mass of intergrown, lustrous, salmon-colored hilgardite, with crystals to 8 mm. The single find was of no more than a few dozen good quality specimens that were recovered by a miner a few years ago.
