Magnetite 矩陣晶體 - 高度: 63 mm - 闊度: 120 mm- 740 g
Very interesting specimen with several black magnetite crystals present here and there, particularly inside the geode and on a side.
It was etched to highlight the magnetites from the calcite where they were embedded.
It is sawn to reduce the volume of the matrix.
