Do lab grown diamonds pass a diamond test?

Yes, lab grown diamonds pass a diamond test. Lab grown diamonds are real diamonds, so they pass the same test to measure quality as natural diamonds do. There’s a little more to it, so read on. If lab grown diamonds are on your wishlist because you love their sparkle and want to maximize your budget, it’s important to understand how Helzberg experts verify their origin, authenticity and quality.

Do lab grown diamonds test as real?

Yes, lab grown diamonds test as real. The equipment available to jewelers analyzes a variety of characteristics — nitrogen levels, fluorescence under UV light and other measurable properties — to determine a diamond’s origin and whether it’s been treated. Aside from a rare false negative, lab grown diamonds test as real because everything else about their physical, chemical and optical properties is the same as a natural diamond.

Can a jeweler tell a diamond is lab grown?

A jeweler can’t tell whether a diamond is lab grown or naturally mined without specialized equipment. Because lab grown diamonds are chemically and optically identical to natural diamonds, a standard diamond tester will read a lab grown diamond as “real.” If a diamond has been certified by a grading laboratory, a jeweler can determine its origin by using a high-powered loupe or microscope to read the number laser-inscribed on its girdle.

Why diamond certification matters

Diamond certification matters because, like diamond testing, it ensures authenticity. More than that, a diamond report provides a clear, unbiased evaluation of your lab grown diamond’s quality. We work with the most respected, specialized grading labs in the industry so you can feel confident about your purchase.

Frequently asked questions

Do lab grown diamonds test as real diamonds?

Yes. Lab grown diamonds test as real diamonds because they have the same physical, chemical and optical properties as natural diamonds. Jewelers use a variety of equipment to test a diamond’s origin and whether it’s been treated. But most commercially available testers don’t recognize the difference between lab grown and natural diamond — that requires specialized equipment.

Do lab grown diamonds test as natural diamonds?

Standard diamond testing tools usually can’t tell the difference between a lab grown and natural diamond because they’re structurally the same. To determine a diamond’s origin takes specialized gemological tools that reveal the way a diamond absorbs and reflects light or shows growth patterns or inclusions.

Are lab created diamonds real?

Yes, lab created diamonds are real diamonds, with the same physical, chemical and optical properties as natural diamonds. That makes them different from other diamond “simulants” like cubic zirconia that share some visual characteristics with diamonds but lack a diamond’s quality, value or durability.
