This incredible specimen from Cornwall, England, is etched with history. Out of a pocket mined in the mid 1800s, this classic piece features bournonite that is lustrous to the point of actual iridescence stemming from oxidization and within which you can see the cogwheel habit unique to this mineral species. The bournonite is growing with a spiky, lustrous cluster of quartz terminations featuring one larger, perfect termination jutting off of the cluster at the top. A strikingly aesthetic, museum quality piece that will elevate even the most impressive of collections.
