Diamond simulants can be a stunning alternative to diamonds but are not compositionally and optically the same as diamonds. Because most diamond simulants are manmade and mass produced, they have no scarcity. A 1 carat moissanite can be purchased for US$25 - $500. A 1 carat cubic zirconia can be purchased for US$1 to $10. As a result, common diamond simulants like cubic zirconia and moissanite are not a store of value and have very limited resale value.
