Lab-grown Diamonds FAQ

Are lab-grown diamonds real diamonds?

Yes, lab-grown diamonds are real diamonds. They essentially have the same chemical composition, crystal structure, and durability as natural diamonds.

What is the difference between a lab-grown diamond and a natural diamond?

The main difference between lab-grown and natural diamonds is their origin. Natural diamonds are formed in the Earth’s mantle over billions of years, while lab-grown diamonds are mass-produced in factories within a matter of weeks.

How are lab-grown diamonds made?

Lab-grown diamonds are created by either High Pressure, High Temperature (HPHT) or Chemical Vapor Deposition (CVD). HPHT recreates the Earth’s intense heat and pressure to form these diamonds, while CVD uses carbon gas in a vacuum chamber. Our lab-grown diamonds are created using both methods.

How much does a lab-grown diamond cost compared to a natural diamond?

Lab-grown diamonds cost significantly less than their natural counterparts. Typically, a 1.00-carat colorless lab-grown diamond costs around $1,000, while its natural equivalent is around $3,000. As carat weight increases, the price gap increases significantly. To find the perfect diamond within your budget, make an appointment with our local diamond experts.

Can you tell if a diamond is lab-grown by looking at it?

To the naked eye, a lab-grown diamond is essentially indistinguishable from a natural diamond. Both can have the same brilliance, polish, symmetry, and color.

What sizes, shapes, and cuts are lab-grown diamonds available in?

Lab-grown diamonds are available in the same sizes, shapes, and cuts as natural diamonds. Not sure which style you want? Schedule an appointment with one of our diamond experts, who will walk you through the process and let you compare different styles side by side.

Do your lab-grown diamonds come with a certification?

Yes, all of our lab-grown diamonds are certified by the International Gemological Institute (IGI) and come with a comprehensive report of your diamond’s characteristics. An IGI certification is also useful for obtaining insurance and protecting resale value.

Why should I buy a lab-grown diamond in a physical store instead of an online store?

When you buy a lab-grown diamond in-store, you can compare different sizes, shapes, and cut qualities at the same time and see how they look on you. Brick-and-mortar stores may also offer ongoing service for your jewelry. At IDC, we’ll help you find a diamond that’s as unique as you and provide complimentary care to keep it looking stunning.

I found the perfect mounting in your showroom. Can I put a lab-grown diamond on it?

Yes, you can add a lab-grown diamond to any mounting. Our expert designers can also create a custom mounting from an image or idea, or personalize an existing one to bring your perfect piece to life. Make an appointment or visit a location to learn more.
