標 本 名: | コンドロダイト / スピネル (Chondrodite / Spinel)
| 化学組成: | (Mg,Fe2+)5(SiO4)2(F,OH)2 / MgAl2O4 | サ イ ズ: | | 重量: | | 透明: | transparent - translucent | 数量 : | | 産地: | Oh Saung Taung, Le-Oo (Le U), west of Mogok, ビルマ(ミャンマー) Burma (Myanmar) | Here you get two Chondrodite crystals with good luster and undamaged shape together with a intact spinel crystal in matrix. I still see these specimens sometimes sold as Norbergite, this is not Norbergite!! The bigger crystal has at one side a tiny cleavage area, there is also another two crystals but only partly terminated. Furthermore they are smaller spinel and chondrodite crystals deeper imbedded in the translucent calcite.
