Synthetic stones often exhibit specific growth curves, gas bubbles, or metallic flux inclusions that are distinct from the natural mineral inclusions found in earth-mined gems. The detailed visual evidence provided by Gübelin and Koivula allows gemologists to identify the tell-tale signs of laboratory creation, protecting both the integrity of the market and the consumer.
