Mineral: | Crisoberilo
| Fórmula química: | BeAl2O4 | Tamaño: | | Peso: | | Transparencia: | | Número de piezas: | | Origen: | Rakwana, Ratnapura, Provincia de Sabaragamuwa, Sri Lanka | Beautiful yellow chrysoberyl crystal disclosing a sixling shape. Sadly one interpenetration twin is not fully crystallized maybe to the fact that the crystal has been connected to its matrix. In the middle the crystal shows typical v-shaped crystal striations. The outer part has been slightly rounded by the fluviatile transport. The crystal shows a yellowish to greenish coloration and predominantly good transparency. Fine chrysoberyl specimen, more rarely found with this crystal shape.
