Buying Tips from Our Gemologists

Most commercial 'blue topaz' is irradiated and heat-treated — lovely but modestly valued. The rare Imperial topaz in golden-orange-pink tones commands far higher prices and is the connoisseur's choice.

Caring for Your Topaz

Topaz cleaves easily on impact. Protect it from hard knocks, clean with warm soapy water, and avoid ultrasonic cleaners for fractured or treated stones.
