North America, United States, Illinois, ca. 350 million of years ago. This is a beautiful collection of 5 shimmering minerals of pyrite and stibnite! The four pyrite discs are fittingly known as pyrite suns, pyrite dollars, miner's dollars, or sun dollars, with the striations radiating from the center. While they look like fossilized sand dollars (sea urchins) these discs are naturally concentrated structures formed by pressure when pyrite is compressed between shale layers and coal seams. While pyrite is found worldwide, pyrite suns are only found in Illinois! Stibnite, also known as antimonite, is a silvery mineral that forms delicate dipyramidal structures, as seen here - absolutely mesmerizing! The silvery mineral has been used for thousands of years: ground into powder for medicine and cosmetics such as kohl eyeliner in Egypt and for fireworks in China! Size of largest pyrite disc: 3.35" W (8.5 cm); stibnite: 2.25" L x 1.5" W x 1" H (5.7 cm x 3.8 cm x 2.5 cm)
Please note that stibnite is toxic if ingested, so while beautiful, we recommend washing hands after handling and storing in a case when displaying.

Condition
Some active flaking of stibnite structures, we highly recommend storing in a case to protect crystalline structures and due to toxicity of stibnite. Pyrite discs are very good with some minor fissures along edges and radiating towards the center.
