“7.6 x 6.7 x 4.0 cm. An impressive ruby specimen from the classic ruby mines here which date back even to Roman times. Large crystals in matrix are rare. Large good crystals in matrix are almost unheard of. This is a rare example of such a piece, with a dominating 3 x 3 x 1.2-cm crystal sticking straight up and completely exposed on either side. The crystal is pristine and complete. Ex. Joe Freilich and Wall Mann Collections.
