Although grown by scientists instead of created in the earth’s crust, lab diamonds are absolutely real diamonds—they display the same chemical and optical properties as natural diamonds.
Even expert gemologists can’t tell the difference, but just for fun we’re offering you the chance to guess. Each of the sets of engagement rings on this page includes one ring featuring a lab diamond and one with a naturally mined diamond. See if your instincts can determine which is which.

Classic Round Lab Diamonds
If you’re looking for a lab grown diamond in a classic round brilliant cut, you’re in luck, because we have an expansive selection of round lab diamonds. When the process of growing a diamond was first invented labs were only capable of creating small diamonds, but today you can purchase lab diamonds up to three carats. (The lab diamond is the one on the right.)
Lab Diamonds in Fancy Shapes & Colors
Lab diamonds are also available in a variety of shapes including emerald, oval, cushion, radiant, princess and asscher. If you love colored gemstones, consider a lab created colored diamond in a fancy shade of yellow or pink. (The lab diamond is the one on the left.)
Lab Diamonds with Natural Accents
If you’d like your ring to feature both a lab diamond and naturally mined diamonds, you can have a lab diamond set in a ring featuring natural accent diamonds. (The lab diamond is the one on the right.)
Impossible to Distinguish
If you couldn’t tell the lab diamonds from the natural ones, we’re not surprised—and if you could you’re just a lucky guesser! Lab diamonds are created in high-temperature, high-pressure chambers that reproduce the conditions in the earth’s crust. The result is carbon atoms arranged in the structure of a diamond crystal and diamonds that are every bit as magical as the ones created naturally millions of years ago and mined today.
Lab diamonds usually cost about 30% less than natural diamonds of comparable size and quality. But these diamonds are every bit as luxurious as their natural counterparts, since their dazzling beauty and durability are the same. It is important to know that there’s a big difference between lab created diamonds and diamond simulants, such as cubic zirconia and moissanite. These simulants are not made of the carbon crystals, and do not possess the same brilliance as diamonds. For that reason, simulants sell at much lower prices than lab created diamonds.
