Item Description

A very strange looking, sculptural pseudomorph from recent Morocco finds. Two-toned, translucent, brown and whitish chalcedony has replaced a weird looking globular sponge. Originally marketed in Europe as being from Smara, Western Sahara, these are actually from these obscure open-pit phosphate mines, that have also produced snow-white quartz geodes (MINDAT). The deposits are Upper Cretaceous - Eocene age, 100-34 MYA.
