This complex, twinned, transparent pale amber-coloured Calcite crystal group on a tiny piece of matrix comes from the famous early 1990s find at Rudny in Kostanay Province, Kazakhstan. Icons of Kazakhstan mineralogy, they present a form instantly recognizable from any other world Calcite, which is a hard task. With virtually no wear, this piece is an extremely fine example, and large, with the largest crystal extending to over 5 cm across. At least four crystals are intergrown, or twinned, with their faces varying between glassy and transparent, to slightly rough and opaque/translucent but all in perfect damage-free state and with lovely growth-lines exhibited too. An exceptional Calcite from this famous discovery.
