This fascinating specimen formed when gemmy calcite crystals grew in the natural pocket formed by a buried fossil clamshell. This one is distinguised in that most of the shell is now gone, so what you are left with is this very pretty cluster of lustrous, gemmy calcite crystals, sitting up aesthetically on a shell conglomerate matrix, and complete all around! This is a very fine calcite specimen even disregarding its interesting means of formation! 4.4 x 4.1 x 2.8 cm
