Lab-Grown Diamonds

What Are Lab-Grown Diamonds?

Scientists create lab-grown diamonds in a lab that are optically, chemically, and physically identical to natural diamonds. These diamonds offer the same luxurious feel at flexible prices to fit anyone's lifestyle. Additionally, they provide the opportunity for a larger carat weight at lower costs.

Optically

Lab-grown diamonds have the same visible qualities as natural diamonds and are indistinguishable from them with the naked eye.

Chemically

Lab-grown diamonds are not simulants. They are formed from rough true carbon crystals, taking an average of 2–4 weeks.

Physically

To confidently tell lab-grown and natural diamonds apart, advanced instruments are needed to detect the physical aspects.

What Is The Difference Between Lab-Grown And Natural Diamonds?

Diamond	Natural	Lab-Grown
Chemical Composition	Carbon	Carbon
Crystal Shape	Octahedron	Cuboctahedron/Cube
Refractive Index	2.42	2.42
Dispersion	0.044	0.044
Hardness	10	10
Density	3.52	3.52
Inclusions/Blemishes	Yes	Yes

How Are Lab-Grown Diamonds Created?

Lab-grown diamonds are created using two methods: high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD). In the HPHT method, a diamond seed is placed in a growth chamber and exposed to extreme heat and pressure, similar to the process that occurs in the Earth's mantle. The CVD method involves placing diamond slabs in a reactor and injecting them with methane gas, which breaks down into atoms and generates a carbon-rich plasma cloud that connects with the diamond slabs and creates new layers. Both methods can produce colorless or colored lab-grown diamonds, which are equal in quality to some of the rare and sought-after types of natural diamonds.

Frequently Asked Questions

What is the benefit of buying lab-grown diamonds?

Lab-grown diamonds present a viable option for consumers to acquire a diamond of superior quality or size at a reasonable cost.

What is the difference between lab-grown diamonds and Moissanite?

Lab-grown diamonds are carbon-based and identical to natural diamonds. Both have a hardness of 10 on the Mohs scale. Moissanite, made of silicon carbide, has a hardness of 9.25.

How do I tell if a lab-grown diamond is real?

Lab-grown diamonds are genuine diamonds, composed of carbon like natural diamonds, with identical optical and physical characteristics. To differentiate between lab-grown and natural diamonds, sophisticated testing and screening are required.

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

What distinguishes a natural diamond from a lab-grown diamond? The only difference is their growth process. Natural diamonds form in nature without human intervention, while lab-grown diamonds are created in a laboratory with the aid of scientists.

What are the 4C's of lab-grown diamonds?

Lab-grown diamonds share the same four Cs as natural diamonds: Cut, Color, Clarity, and Carat Weight. Learn more about the 4C's of lab-grown diamonds.
