Description
According to mindat.org, La Serna is one of the many quarries for clay extraction in the La Sagra Region of Castilla-La Mancha in central Spain. Some of the marl layers contain vugs with radial Aragonite aggregates such as this 2.6 cm measuring spherical cluster of acicular, clear, slightly ocher-colored Aragonite crystals on typical clay marble matrix. A pretty piece, very aesthetic!
