What is Chalcopyrite?
Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years.
The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering. It tarnishes to a dull, gray-green color, but in the presence of acids, the tarnish can develop a red to blue to purple iridescence.
This Stone is Chalcopyrite and is hand-made by Ernie from the Rough. Cutting, Shaping (Free Form), Grinding, and Polishing, and finishing with a 20' Gold plated snake chain necklace. The stone is approximately 11 grams / 55 ct with bale. I take pride in my pieces and put a lot of time into finishing them. I like to use a bale as it doesn’t take from the stone. Great gift for any occasion. Please share your findings with family and friends.
