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.
- Overpaying at one retailer without comparing the same color and carat elsewhere.
- Cleaning it the wrong way. Can abrade at facet edges. Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners and prolonged sunlight.

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.
