Lab Grown vs Cubic Zirconia

What is the difference between lab grown diamonds and simulated diamonds?

Diamond simulants and lab-grown diamonds are completely different. A diamond simulant is not a diamond at all, because the chemical properties are completely different. Simulants can be made out of anything from glass to cubic zirconia. While they may look similar at first, diamond simulants aren’t as hard and don’t have the same optical properties as diamonds, so they’ll show signs of wear and won’t be as sparkly. In contrast, a lab grown diamond is chemically the same as a natural diamond and will be long lasting with the same fire and brilliance.
