Also known as diamond simulants, these stones are similar to diamonds in their appearance but different in their physical and chemical properties. You’ve likely heard of a few different kinds of diamond simulants, including cubic zirconia and moissanite. There are also a few gemstones that can fall into this category because of their clear appearance. These include quartz and white sapphire.
Synthetic diamonds, on the other hand, are chemically, physically, and optically the same as mined diamonds. They are also known as lab-grown diamonds, man-made diamonds, or cultured diamonds. In all intents and purposes, they are real diamonds. The only difference is where they were created. Although they are synonymous, the Federal Trade Commission has actually ruled it deceptive to classify a lab-grown diamond as ‘synthetic’ since this term can be misleading. For the most part, you will find these diamonds labeled by one of their more appropriate names.
