Balangoda, Ratnapura, Sabaragamuwa Province, Sri Lanka 2.0 x 1.9 x 1.5 cm. A superb, gemmy and lustrous, honey-brown, V-twinned chrysoberyl crystal from the famed Ratnapura area of Sri Lanka. This complete all-around and undamaged beauty has textbook crystal form. A couple of the edge faces are frosted/contacted, but there is no damage, per se and the classic form is certainly not diminished. |
