what is a simulated diamond

A simulated diamond is an object or material that has gemological characteristics similar to those of a diamond, but is compositionally and optically different from a diamond. Simulants are distinct from synthetic diamonds, which are actual diamonds exhibiting the same physical and chemical properties as a natural diamond. Simulated diamonds are created to mimic the look and feel of a mined diamond, but are made out of various materials and do not have the same chemical composition as a mined diamond. Some popular diamond simulants include cubic zirconia, moissanite, topaz, and white sapphire. Simulated diamonds are often less expensive than both genuine and lab-grown diamonds, making them an appealing low-cost alternative for many people. However, they are not as valuable as diamonds because they are not the same compositionally and optically as diamonds.
