Buying Tips from Our Gemologists

Color is king: the deeper, more saturated blues are rare and costly, while pale stones are abundant and inexpensive. Heated stones achieve the vivid blue; unheated pieces with natural color are premium.

Caring for Your Aquamarine

Aquamarine is durable but brittle at the girdle. Clean gently with warm soapy water and keep it separate from harder stones in storage.
