40 Facts About Pyrargyrite

What is Pyrargyrite?

Pyrargyrite is a fascinating mineral known for its deep red color and metallic luster. Often referred to as "ruby silver," this mineral has captivated collectors and scientists alike. Let's dive into some intriguing facts about pyrargyrite.

1. Pyrargyrite is a sulfosalt mineral composed of silver, antimony, and sulfur.
2. Its chemical formula is Ag3SbS3.
3. The name "pyrargyrite" comes from the Greek words "pyr" (fire) and "argyros" (silver), referring to its fiery red color and silver content.
4. Pyrargyrite is often found in hydrothermal veins, where it forms alongside other silver minerals.
5. It has a Mohs hardness of 2.5, making it relatively soft.
6. The mineral has a specific gravity of 5.85-5.90, indicating it is quite dense.
7. Pyrargyrite crystals are typically prismatic, but they can also form massive or granular habits.
8. The mineral is opaque, with a metallic to sub-metallic luster.
9. Pyrargyrite is known for its deep red to black color, which can appear almost metallic in certain lights.
10. When exposed to light, pyrargyrite can darken over time, a process known as "tarnishing."
