Every color stone has its unique colors and qualities, and therefore, treatments or enhancements may differ.
Natural Gemstones may have been treated. Please visit our Gemstone Guide for more information about specific gemstones treatments.
Natural gemstones may have been color and/or clarity treated by various enhancement processes including including, but not limited to, heating (generally); oil/wax/resin (emeralds, opal, tourmaline, turquoise); diffusion (sapphires, rubies, topaz); irradiation (some color diamonds, topaz, tourmaline, morganite); fissure-filled with a glass-like by-product (rubies); or dyed (chalcedony, sugilite). Treatments may not be permanent and/or may require special care. Our trained professionals are knowledgeable in repairing jewelry that contains treated gemstones.
Exposing gemstones to extreme heat, excessive light, chemicals and ultrasonic, steam or abrasive cleaning should be avoided. Generally, gemstones should only be gently cleaned by rinsing in warm water and drying with a soft cloth. Proper care is required in jewelry repair as extreme heat can damage gemstones and/or treatments.
It is our policy not to sell or trade in gemstones that have been treated with vapor deposition. Also, we do not sell rubies from Myanmar/Burma, composite rubies, coral or ivory.
