An exceptional piece. Group of Dolomite crystals, two of them clearly dominant, on a matrix covered by crystals of smaller dolomites. The crystals are extraordinarily transparent and lustrous, twinned, and with very well defined faces and edges, perfect.
An old specimen, from the now extinct Asturreta Quarry in Eugui. A classic of Spanish mineralogy of very notable quality.
