標 本 名: | クリソベリル (Chrysoberyl)
| 化学組成: | BeAl2O4 | サ イ ズ: | | 重量: | | 透明: | | 数量: | | 産地: | Rakwana, Ratnapura, Province of Sabaragamuwa, スリランカ (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.
