鎂鐵礦與石英的美妙結合 --- 基質上的晶體 - 高度: 15 cm - 闊度: 11 cm- 1440 g

由Luca Esposito精選

Very nice specimen with association fo tabular black bright ferberite crystals, with vertical streaks, at the base of a nice group of quartz crystals. The ferberite formation measures 4 cm in length and is perfectly terminated. The quartz crystals are partially covered by muscovite in association with small crystals of apatite. The 10 cm measurement is the overall thickness of the matrix up to the top of the tallest quartz crystal.
