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 3.25) in an exposed daily-wear ring instead of a protective bezel or halo.
- Cleaning it the wrong way. Soft and fragile, and the color can fade in sunlight. Dust gently and keep out of bright light. Avoid water and ultrasonic cleaners.
