Lab Grown Horizontal Set Oval Cut Diamond Half Eternity Ring A lab-grown diamond has the same makeup as a natural diamond, with one major difference?instead of growing in the earth, it?s grown in a laboratory. No visual difference can be discerned between natural and lab-created diamonds: they sparkle just the same, have the same grades of color and clarity, come in the same sizes and shapes, and measure the same on Moh?s scale of hardness. Are Lab Grown Diamonds Real Yes! Lab-grown diamonds are real diamonds, in the sense that they are exactly the same as natural diamonds, only they?re grown and not found. In fact, because of the identical chemical and visual properties to natural diamonds, the Federal Trade Commission (FTC) recognized lab diamonds as real in 2018. While organically-grown diamonds can take billions of years to form, those grown in the lab can be done in just a few weeks?the process is similar, it?s just on high speed. Diamond Carat Weight: 1.5
