Andilamena District, Alaotra-Mangoro Region, Toamasina Province (Tamatave), Madagascar
A very nice smoky Japan-law twin quartz crystal from the Marovaolavo Mine in Andilamena, Toamasina Province, Madagascar! This crystal exhibits interesting skeletal faces that show lots of growth hillocks and cavities. The twinning is well-defined and the crystallization is sharp. The crystal is quite gemmy and is undamaged.
