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.
