Color Stone Enhancements
In addition to gemstone cutting, over the centuries we have developed countless other methods to improve upon the natural properties of gemstones and pearls. These techniques are known as enhancements. They derive from our desire to draw from nature's bounty the truest and purest color and brilliance.
To bring out the beauty of natural gemstones, they may have been color and/or clarity treated by: heating (generally); oil/wax/resin(emeralds); diffusion (sapphires, rubies, topaz); or fissure-filled with a glass-like byproduct (rubies, sapphires). Although most treated gemstones are stable, some may require special care in jewelry repair. Our trained professionals are knowledgeable in repairing jewelry that contains treated gemstones. Gemstone jewelry should only be gently cleaned by rising in warm water and drying with a soft cloth. It is our policy not to sell or trade in gemstones that have been treated with vapor deposition. We do not sell irradiated gemstones that are governed by regulatory requirements pertaining to the process by which they are treated. We do not sell rubies from Myanmar/Burma. We do not sell composite rubies. We do not sell coral. All of our policies follow standards set by the jewelry industry.
