Caring for Aquamarine Jewelry:

Aquas are rated 7.5-8 on the Mohs hardness scale, making them suitable for daily wear. 

Aquamarines can be heat treated to enhance color and increase availability of quality gems in the industry.

No special care is required for heat treated gems.  Wear with (love and) care.  Clean with warm soapy water and a soft bristle toothbrush.  Chemicals and abrasive cleaners should be avoided on all fine jewelry.
