Everything You Need to Know about Buying a Lab Diamond Ring

Lab grown diamonds provide consumers with a “real” diamond that shares the same chemical composition, optical properties and physical features as natural diamonds. Keep reading to learn more about With Clarity lab grown diamonds including benefits, pricing and how to select the perfect stone and setting.

What is a Lab Grown Diamond?

The process to create a lab grown diamond is similar to the process to create natural diamonds–the only difference is one occurs within the earth’s crust and the other occurs in a laboratory. To create a lab grown diamond, the manufacturing process replicates conditions that create a natural diamond creation–extreme temperatures and pressures that turn carbon into a diamond.

Manufacturers have two ways to create lab diamonds–High Pressure High Temperature (HPHT) and Chemical Deposition (CVD):

Jewelry can be engraved any time, either during or after purchase. If the jeweler is unable to do ring engraving, they should be able to direct you to an engraver. Some world-renowned grading labs, like the Gemological Institute of America (GIA), also perform special gemstone engraving. If you're not partial to the idea of inscribing a visible message, consider engraving the message on the gemstone itself. The GIA can laser-inscribe a microscopic message or graphic on the diamond, creating a special hidden message privy to just you and your partner. A laser-inscribed message also serves as a foolproof identifier in case your jewelry is ever lost or stolen.

HPHT:A diamond “seed” is added to carbon. A diamond seed is a small natural diamond fragment that can undergo both extreme temperature and pressure conditions. The HPHT diamond growth process subjects diamond seed and carbon to extreme temperatures (in excess of 1,300-1,600 degrees celsius) and pressures (one million pounds per square inch) to replicate the extreme heat and pressure conditions deep within the earth where natural diamonds form. The carbon forms around the diamond seed and is then cooled.

CVD:The chemical vapor deposition system begins with a diamond “seed.” It’s important to select the strongest and highest grade (in color and clarity) natural diamond bit. During the CVD process, the vacuum chamber in which the diamond seed is placed fills with gases that are heavy in carbon and is then heated to well over 1,000 degrees. The intense heat then turns the gases into “plasma.” The plasma is what helps “build” the layers of the diamonds.

Each lab diamond takes about a month to produce and then it’s cut and polished like a natural diamond.

Common Lab Grown Diamond Myths

A common myth about lab grown diamonds is that they’re not “real” diamonds. However, lab grown diamonds have the same optical, physical, and chemical properties as a natural diamond.

Another myth is that lab diamonds are imitation diamonds, which is untrue. Actual imitations like cubic zirconia or synthetic moissanite look like diamonds but have different chemical and physical properties.

Lab Grown Diamond Benefits

Lab grown diamonds have numerous benefits in addition to cost, which we will discuss shortly:

Durability: They remain the hardest material on earth—a 10 on the Mohs hardness scale—and are as difficult to chip as a natural diamond.

Ethically sourced and conflict free: Unlike most natural diamonds, you can pinpoint the origin of lab grown diamonds.

Environmentally friendly: The environmental impact is much reduced, mined diamonds have a huge impact upon environments, landscapes and communities.

Lab grown diamonds have plenty of pros, but they aren’t as valuable long-term as natural diamonds because natural diamonds are rare.

Lab Diamond Pricing

Lab grown diamonds are more affordable in comparison to natural diamonds. You can expect to pay 15% to 30% less on a lab diamond than you would on a mined diamond. This price difference is because mined diamonds go through a longer supply chain and require more costly resources.
