Calcite on Calcite

A gorgeous lemony yellow twinned crystal is set upon a calcareous matrix with a small twin set below. Originally identifies as coming from the La Florida Mine and later corrected. I did check and the correction is accurate. The way the prominent crystal rests on the matrix is perfection. Ex Kenny Gay collection.

Locality: La Cuerre Mine, La Florida District, Cantabria, Spain

Composition: calcium carbonate
