10K Solid Yellow Gold Vintage Emerald Ring Size 6 - Creating gemstones in a lab is an art that must be learned and perfected using imagination and skill. Lab created gemstones are not imitations, they are newly created gemstones that are of the same make up as the mined gemstones. So by definition, gemstones created in a lab cannot be called synthetic because rather than imitate a gemstone…they ARE gemstones.
