Gemstone Treatments

Here at Dubin's Fine Jewelry, the vast majority of our diamonds and gemstones are untreated. However, a number of gemstones undergo some form of treatment in order to enhance and/or stabilize certain color and/or clarity properties. We strive for complete transparency when it comes to each and every item and below are two treatments that some of our products receive. For more information please contact us.
