Man-Made Diamonds (Lab-Created Diamonds)

Man-made diamonds (or lab-created diamonds) are real diamonds that are grown in laboratory conditions that simulate the earth’s natural growing environment, producing results that are optically, physically and chemically identical to mined diamonds. We use scientifically advanced techniques that produce real diamonds that will pass all tests used to confirm a pure carbon diamond. All of our lab-created diamond jewelry comes with either EGLUSA or IGI certified grading reports, but we also offer our own satisfaction guarantee to make sure you’re completely happy with the results. These simple, pure and elegant alternatives to earth-mined diamonds are affordable, beautiful and sustainable. Take a look at our collection to find the piece that is perfect for you.

Diamond Creation

Our lab-created diamonds are grown using two different techniques. Each process produces pure carbon diamonds, but they are sometimes used in different situations. High Pressure High Temperature (HPHT) is our main growing process, but we can also use Chemical Vapor Deposition (CVD) to produce diamonds for industrial purposes. Learn more about how our man-made diamonds are created.


Many different factors can contribute to the availability of certain man-made diamonds, including size, color, and growth process. They are currently being grown around the world in many different labs, and while yellows, oranges, blues, and pinks are readily available, whites are usually less available in sizes over 1.5 carat. Learn more about man-made diamond availability.


Lab-created diamonds are usually 10% to 25% the cost of their natural diamond equivalents. But buyers should beware: Genuine lab-created diamonds that actually have the quality standards you want will never be sold for only a few hundred dollars per carat – don’t be fooled when the deal is too good to be true. Only Diamond Simulates can be priced for a few hundred dollars. Learn more about how lab-created diamonds are priced.
