Iron Pyrite Cluster 40 - 60 grams

"These Iron pyrite crystals clusters contain easily identifable octahedral crystals, making them a good teaching example. They have the same crystal structure as our large pyrite clusters but are smaller. Each piece weighs between 40 and 60 grams. The brassy, yellow color is brilliant with lots of sparkle. This is a sample of our inventory. Each piece is different but all are comparable to the one in the picture."
