Pyrite pros and cons
Pros
- Strong value for the look
- Usually sold untreated
Cons

Common buying mistakes
- Buying on carat weight alone instead of color and cut, which drive beauty more.
- Skipping treatment disclosure, which changes both value and care.
- Setting this softer stone (Mohs 6.25) in an exposed daily-wear ring instead of a protective bezel or halo.
- Cleaning it the wrong way. Can tarnish and is sensitive to moisture. Wipe with a dry soft cloth. Avoid water, humidity, and chemicals.
