You have seen this combination from Mali recently, but most likely in dinky specimens. This is quite an uncommon LARGE and incredibly rich specimen of the combo: dark green, chisel-tipped epidote crystals, maybe 100 of them, piled up atop one another, with translucent balls of green prehnite decorating them. If you have been waiting for a "significant" specimen from this find, perhaps this is it.12.5 x 11 x 9 cm
