A diamond by definition is a mineral created by nature; a “diamond” always means a natural diamond. As often happens with extraordinary objects, imitators abound and can lead to consumer confusion. A synthetic diamond, by definition, is an artificial product that has essentially the same physical characteristics as a diamond. They are sometimes marketed today as “laboratory-grown”, “cultured”, “created”, “cultivated”, “synthetic”, “simulated”, or “man-made”, but it's important to understand the difference between a diamond and these products because by definition, they are not diamonds.
The lab grown gems hitting the market give the question a sense of urgency....
What is a diamond? I have been giving the question a lot of thought lately with the abundance of lab grown diamonds hitting the market. A scientist will tell you a diamond is pure carbon. I believe it is much more.
In January 2018, nine leading international diamond and jewelry industry organizations agreed on a universally-accepted diamond definition. Their goal was to help consumers avoid confusion given the proliferation of marketing terms they encounter increasingly in the marketplace, such as “cultured”, “laboratory-grown”, “created”, “cultivated”, “synthetic”, “simulated”, or “man-made”. These products, by definition, are not diamonds.
