| 化学組成: | Al2O3 | サ イ ズ: | | 重量: | | 透明: | | 数量: | | 産地: | Mine near the village Kollane, Embilipitiya (Embilipitya; Ambilipitiya), Province of Sabaragamuwa, スリランカ (Sri Lanka) | Here you get the pinkish to violet colored Geuda Sapphire crystal. One termination shows a tiny fracture plane while the rest of the crystal is fully intact , also a tiny rutile crystal is attached. One part of the crystal shows an imprint of the former neighbor crystal but the tiny pit is fully crystallized. This corundum crystal shows an unusual surface which seems to be post- genetic altered so the former striations is hardly visible at some parts. A typical Geuda Sapphire with a strong typical ”Diesel”-appearance.
