Unlike diamond simulants (imitations of diamond made of superficially similar non-diamond materials), synthetic diamonds are composed of the same material as naturally formed diamonds—pure carbon crystallized in an isotropic 3D form—and have identical chemical and physical properties.

Lab grown diamonds are real diamonds produced in a controlled setting. They are grown in two ways: a High Pressure, High Temperature (HPHT) process that mimics their natural formation in the Earth, or a Chemical Vapor Deposition (CVD) process.

Mar 5, 2025 · Synthetic diamond, man-made diamond that is usually produced by subjecting graphite to very high temperatures and pressures. Synthetic diamond resembles natural diamond in most fundamental properties, such as extreme hardness, broad transparency, high thermal conductivity, and high electrical resistivity.

Dec 11, 2024 · With new technologies and sustainable practices, lab-grown diamonds are becoming an increasingly popular choice among jewelry shoppers. They’re chemically and physically identical to...

Dec 13, 2016 · Synthetic diamonds are real diamonds, but they’re not the same as natural diamonds. Shopping for a diamond? Here is everything you need to know about synthetic diamonds!

Sep 22, 2017 · Man-made diamonds have been produced for industrial purposes since the 1950s and are used in a wide variety of applications: telecommunications, laser optics, healthcare and more. In 1970, researchers at General Electric created the first, small, gem-quality synthetic diamonds that could be faceted as gems.

Optically and chemically identical to natural diamonds, lab diamonds offer a new approach to brilliance. Ethical, eco-conscious and endlessly beautiful. Shop affordable, high-quality IGI and GIA lab grown diamonds for rings, earrings and more at Blue Nile.

We created the GIA iD100 ®, a desktop instrument to help jewelers distinguish natural diamonds from laboratory-grown diamonds, diamond simulants and some treated diamonds in under two seconds. Laboratory-grown diamonds can also be sent to …

Feb 25, 2025 · Lab diamonds, also known as synthetic diamonds or artificial diamonds, are less expensive than natural diamonds but have a lower resale value. Still, lab-created diamonds can be a beautiful alternative to an engagement ring.

Feb 27, 2025 · Lab-created diamonds (which have also been referred to as lab-grown diamonds, synthetic diamonds, artificial diamonds, cultivated diamonds or cultured diamonds) are man made diamonds that mirror natural diamonds.
