Gem Library
Synthetic colored gemstones are becoming quite common in the market, so, as always, know your seller and be careful of any material that looks “too good to be true”. Du Lyon Jewelers does not knowingly deal in synthetic stones and every gemstone that we sell has been examined by a Graduate Gemologist to confirm its natural origin whenever possible.
