Quartz Crystal Cluster with some Pyrite. Bulgaria

You will get the actual piece shown in the images.

Really splendid display piece which has small thin perfect little quartz crystals radiating out from the centre.
There looks to be some golden chalcopyrite revealed on the edge and another mineral which could perhaps be cassiterite (tin) or sphalerite (zinc).
I have a feeling this came from a collector originally who worked minerals from mines in a region of Bulgaria but you might need
to do a little research to find similar to confirm the exact region as there are several mines there producing nice specimens of this.

From my personal collection selling off after 25-30 years
