Description

Beautiful assemblage of more or less mamelonned green malachite, a little blue azurite, and tetrahedrite in automorphous crystals or sometimes massive in a red limonite gangue.
This piece comes from an absolutely unknown locality.
It comes from the town of Sidi Ghiles (formerly Novi), on the north coast of Algeria.
The mineralogical specimen bears an old handwritten label and was collected around 1880.
