Lab Grown Diamonds FAQs

The first commercially successful lab grown diamond was produced nearly 70 years ago. Working at GE’s lab in upstate New York, Tracy Hall put his Doctorate to work turning carbon into diamonds using a crude pressure chamber fashioned out of a steel belt. GE rewarded him with a $10 savings bond. Hall’s experiment gave rise to the lab grown diamond industry dominated by two main players: GE Superabrasives and De Beers Industrial Diamond Division. These earliest lab grown diamonds were used for cutting and grinding in applications ranging from optics and semiconductors to medical technology. Only in the last few years have gem quality lab grown diamonds exploded onto the market.

Lab grown diamonds are the crystals of carbon atoms, formed under high temperature and pressure, just as mined diamonds are. Lab grown diamonds are produced using technology that replicates the conditions under which these diamond crystals, also known as rough diamonds, are formed underground. Once they are big enough, the lab grown diamonds are cut and polished by master diamond cutters using the same tools and techniques used to cut earth-mined diamonds.

Lab grown diamonds are produced using one of two gem-quality diamond creation processes: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). In both, a small diamond seed is placed in low pressure microwave chamber containing carbon. Hydrogen and methane gases are introduced to start the process. A plasma ball ignites, carbon molecules rain down on the seed and it begins to form layer by layer. Approximately 4-6 weeks later, the diamond is ready to be cut and polished.


LovBe’s colorless diamonds are grown in laboratories across the world using the CVD process.

Lab grown diamonds are grown using a tiny seed of pure carbon. Depending on the laboratory growing them, the seed can be either mined or lab grown. LovBe’s lab grown diamond seeds are grown in labs.

Our diamond experts at LovBe have carefully vetted the labs known for growing the most stunning and brilliant diamonds worldwide. We work exclusively with premier state-of-the-art laboratories to grow our remarkable LovBe lab grown diamonds.

LovBe lab grown diamonds are cut in the same key global polishing centers and in the same highly precise manner as earth-mined diamonds.

LovBe Lab Grown Diamonds are available in a range of shapes, including round brilliants, princess and emerald-cuts, as well as oval, pear, cushion, and radiant cuts.

YES! A LovBe Lab Grown Diamond has identical chemical, physical and optical properties to an earth-mined diamond. As testimony to this, the Federal Trade Commission removed the word “natural” from the basic definition of diamond in 2018. That benchmark decision establishes that there is now more than one way to create a diamond.

LovBe’s Lab Grown Diamonds are certified by independent grading laboratories where gemologists inspect and grade them. The certificate verifies that each stone meets the rigorous standards set by industry. This certificate is included with your purchase.

As a LovBe Lab Grown Diamond is a diamond, we recommend cleaning it exactly the same way you would clean any other diamond. Using a steam or ultrasonic cleaner designed especially for jewelry is highly effective. Alternatively, you can take your diamond to a jeweler for a professional clean.


For a quick, DIY option, fill a small bowl with hot water, mixing in a drop or two of dishwashing soap. Place your ring in the mixture for 5 minutes. Soaking should be sufficient, but if your ring is cloudy from lotions or hair styling products, use a soft bristle toothbrush to gently brush around the stones. Do not be rough, as you may loosen the stones over time.

Remember not to over-clean your diamond jewelry. The industry standard is to clean your ring at home monthly; take it to your jeweler twice a year for a professional cleaning and check that the setting is secure.

The production cycle of lab grown diamond can typically take about 4-6 weeks to reach the desired size of a rough (uncut) diamond. Once it’s the desired size, the rough lab grown diamond must go through the process of cutting, polishing, and certification, just like diamonds from mines do.

The entire process—from seed to mounted jewelry—averages 6-8 months.

No, it isn’t that simple. The lab diamond growing process merely sets the stage to make it possible for diamond crystals to grow in sophisticated growth reactors. The results yield a mixed range of colors and clarities just like those mined from the earth.
