Both halves of an olive green colored Datolite which has been cut and polished to a high finish. Around the edges, there is a white rind with dendritic black intrusions surronded by more white. This is a very obscure, old mine near Copper Harbor which is deep in the forest with any access road long grown over. Specimens from this mine are seldom available.
The specimen is in good condition with a very good high polish but there are some internal cracks.
