標 本 名: | 電気石 (Tourmaline), Variety: リチア電気石 (Elbaite) (ルベライト (Rubellite))
| 化学組成: | Na(Li1,5AL1,5)Al6(BO3)3[Si6O18](OH)3(OH) | サ イ ズ : | | 重量: | | 透明: | translucent - transparent | 数量 : | | 産地: | Mine close to Letpanhla village near Mount Pyin Kyi Thaung, Singu Township, Mandalay Division, ビルマ(ミャンマー) Burma (Myanmar) | This 電気石 (Tourmaline) cluster has 3 tiny spots with some crystalline fracture faces, anything else is terminated. These areas are hardly seen with naked eye so I would call it almost a floater 結晶 crystal. The 結晶 crystal consists dozen of small far and wide grown 結晶 crystals as well as some 白雲母 (Muscovite) in between.
