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 3.5) in an exposed daily-wear ring instead of a protective bezel or halo.
- Cleaning it the wrong way. Very soft and fragile. Keep as a display specimen, dust gently, and avoid water, handling pressure, and ultrasonic cleaners.
