Copper (cubic xls) ex George English circa 1910

Item Description

This sharp copper is the rarest crystal habit of Michigan copper, CUBIC, with stacked cubic copper crystals in a cluster, forming a tower and perched nicely on matrix ! The largest cubic crystal is 1.5 cm tall, elongated in a rectangle as you can see so clearly. This is a particularly dramatic specimen for the crystal habit, but also how it is so well displayed. minor presence of a quartz in the cluster. Note the provenance, and the fact that the cluster rises so treelike from matrix, and this is an exceptional specimen. Ex George English (label dated June 4, of 1910).

Valued $4500-6000, as this is surely one of the more rare and stylish coppers you will see in the size range, for this habit.
