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. Soft and porous. Wipe with a soft damp cloth only. Avoid acids, cosmetics, heat, and ultrasonic cleaners.

Always confirm treatment and the return window before buying. AltGems prices are general per-carat guides, so verify value with a certified gemologist or GIA report.
