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. Extremely hard and durable. Clean with warm soapy water and a soft brush, and ultrasonic cleaners are generally safe.
