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) in an exposed daily-wear ring instead of a protective bezel or halo.
- Cleaning it the wrong way. Soft and brittle. Clean with a damp soft cloth and mild soap. Avoid ultrasonic cleaners, heat, and hard knocks.
