Heat treatment takes place when gemstones are exposed to high temperatures to permanently enhance their color and clarity. Without heat treatment, fine-quality gemstones would be inaccessible to almost anyone. Colored gemstones have undergone treatment for thousands of years. As long as the treatment is permanent, it is widely accepted that enhancements are important for maintaining the popularity of genuine gemstones.
Care guidelines for heated gems:
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.

FAQ
What are treatments?
Natural gemstones are mined from the earth and come in a range of qualities. The quality of a gem is based on their color, cut, clarity and carat weight. Treatments are used to enhance earth mined gemstones to improve quality so that they can be used in jewelry.
Treatments can affect the value of a gemstone so it is important to know if your gem is treated before you buy to make sure you're getting the value you are paying for. If you're interested in learning more about treatments visit our blog here.
