Time it will take natural diamonds around 3 billion years to form whereas, using a laboratory setting, it takes a mere matter of months to create man-made diamonds.

Ethics

Lab grown diamonds are often thought to be more ethical than natural diamonds, as being created in a lab, they are entirely traceable and provide an ethical alternative to naturally mined diamonds.

Cost  

Typically, lab diamonds are around 30% less expensive than natural diamonds. This is because the process used to create lab diamonds takes considerably less time than the billions of years it takes for natural diamonds to form.

Nitrogen

Natural diamonds contain tiny amounts of nitrogen, which lab diamonds do not. This is one of the ways geologists are able to identify lab created diamonds.

Value

This is still being disputed between jewelers as lab diamonds are still newcomers to the industry, and the long-term value is not yet settled. From the introduction of lab diamonds, the demand for natural diamonds has decreased but they are often a much higher quality than ever before, meaning their value has stayed pretty consistent over time.

Grading

Lab diamonds are often graded slightly different to natural diamonds. A GIA certificate would not grade lab diamonds on the same strict scale so you may be inclined to choose another type of certification for your lab diamond. Learn more about diamond certification now.

Similarities between lab and natural diamonds

Aesthetics

There is no visible difference between a lab created diamond and a natural diamond. They both have the same sparkle, and have the same different types of color and clarity. They’re also just as hard as natural diamonds, both containing the carbon element.

Both are ‘real’ diamonds – as lab grown diamonds have the same chemistry and physical appearance as natural diamonds, they are also deemed as real diamond. The Federal Trade Commission (FTC) recognized Lab Diamonds as real in 2024.

Longevity

 As natural diamonds do, lab grown diamonds will last forever, as they are designed with the same chemistry and physicality identical to a natural diamond.

Inclusions

In short, lab diamonds have only very subtle physical differences that only gemmologists would be able to distinguish between but, on the most part, they are identical to naturally grown diamonds, for a more affordable price.

What Is lab diamonds and natural diamonds

Interested in finding out what lab grown diamonds are, and how they differ from natural diamonds? This guide has you covered. Read on to learn the differences between the two and, perhaps more interestingly, how similar both man-made diamonds and naturally sourced diamonds are to each other.

What Is A Lab Diamond?

A Lab Grown diamond, also known as a man-made diamond, is a diamond which is created in a high-temperature and high-pressure laboratory setting. This specific setting creates a diamond which identically replicates the same chemistry, physicality and visual properties of a naturally grown diamond.

What Is A Natural Diamond?

A Natural Diamond is the hardest natural known substance on Earth. Made from carbon, naturally grown diamonds are created over a 1- 3-billion-year time period in very high-pressure and high-temperature natural conditions.

They are also formed at least 85 miles below the Earth mantle. These are the conditions which are replicated when creating lab grown diamonds, in order to create an authentic diamond with the same properties of a natural diamond.
