What is the real name for Peacock Ore?
Bornite
Bornite, also known as peacock ore, is a sulfide mineral with chemical composition Cu5FeS4 that crystallizes in the orthorhombic system (pseudo-cubic).
What element is Peacock Ore?
Copper
| Physical Properties of Bornite | |
|---|---|
| Chemical Classification | Sulfide |
| Chemical Composition | Copper iron sulfide, Cu5FeS4 |
| Crystal System | Orthorhombic |
| Uses | Primarily an ore of copper. |
What’s the difference between bornite and chalcopyrite?
Bornite freshly broken is brown and quickly tarnishes blue. Chalcopyrite does not tarnish.
Is bornite the same as Peacock Ore?
Bornite is an ore mineral of copper, and is known for its iridescent tarnish. “Peacock Ore”, which is sold to amateur mineral collectors and tourists, is often labeled as a variety of Bornite. However, most Peacock Ore in reality is Chalcopyrite treated with acid, which produces a strongly-colored iridescent tarnish.
How can you tell if chalcopyrite is real?
However, if accuracy is important, one can usually tell the difference by chipping a small piece off. On genuine bornite, the broken surface will be brown and tarnish very quickly. On chalcopyrite, the inside will be a shiny silver/gold, metallic-looking surface, and will remain that color.
What does chalcopyrite look like?
The most obvious physical properties of chalcopyrite are its brassy yellow color, metallic luster, and high specific gravity. These give it a similar appearance to pyrite and gold. Gold is soft, has a yellow streak and has a much higher specific gravity. Chalcopyrite is brittle and has a greenish gray streak.
What mineral group is chalcopyrite in?
Sulfide mineral
| Chalcopyrite | |
|---|---|
| Category | Sulfide mineral |
| Formula (repeating unit) | CuFeS2 |
| Strunz classification | 2.CB.10a |
| Crystal system | Tetragonal |
Is peacock chalcopyrite natural?
Peacock Ore (Bornite) is a crystalline variety of Chalcopyrite and they have very similar properties. Bornite is the name of the natural, untreated stone, while Peacock Ore usually describes its heat-enhanced state. Bornite has naturally occurring rainbow colors, but they are rare in nature.

How do you identify chalcopyrite?
The most obvious physical properties of chalcopyrite are its brassy yellow color, metallic luster, and high specific gravity. These give it a similar appearance to pyrite and gold. Distinguishing these minerals is easy. Gold is soft, has a yellow streak and has a much higher specific gravity.
Where is chalcopyrite most commonly found?
