Jasper pros and cons
Pros
- Good durability (Mohs 6.75) for most jewelry
- Strong value for the look
- Usually sold untreated
Cons
- Softer at Mohs 6.75, best in protected settings
- Opaque, so it shows color rather than sparkle
Jasper is ideal for earrings, pendants, and occasional-wear rings, and works in everyday rings with a protective setting.

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 6.75) in an exposed daily-wear ring instead of a protective bezel or halo.
- Cleaning it the wrong way. Durable. Clean with warm soapy water and a soft brush. Generally safe but avoid harsh chemicals.
