Gmelinite-Ca
Sarbai Deposit, Rudny, Kostanay Region, Kazakhstan
7.9 x 5.9 x 5.1 cm. Rudnyi is best known for its beautiful yellow calcites, but here is a rare zeolite from the locality: a rich specimen of gmelinite, with translucent, salmon-colored crystals that are quite sizeable and eye-visible covering the entire face of the matrix.
