Lab Grown Diamonds: Everything You Need to Know

Are Lab Grown Diamonds Real?

Yes, they are real diamonds. Lab grown diamonds consist of carbon atoms arranged in the diamond crystal structure. According to the GIA, they share the same chemical composition and physical properties as natural diamonds, making them virtually indistinguishable to the naked eye.

What Is the Difference Between a Simulant and a Lab Grown Diamond?

Simulants, like cubic zirconia and moissanite, mimic the look of diamonds but do not share the same chemical and physical properties. They are not as durable or brilliant. Lab grown diamonds, on the other hand, are genuine diamonds with identical optical and chemical properties to mined diamonds.

Are Lab Grown Diamonds Simulants?

No, they are not. Simulants are not real diamonds and are often used in costume jewelry. Always verify your diamond’s authenticity to avoid confusion caused by misleading marketing.

What Is the History of Lab Grown Diamonds?

Lab grown diamonds were first created in the 1950s by General Electric for industrial use. Only in recent years have advancements allowed the production of gem-quality diamonds suitable for jewelry.

What Happens When a Diamond Tester Is Used on a Lab Grown Diamond?

A standard diamond tester will identify lab diamonds as real. However, moissanite testers may give false readings. Make sure to use the correct testing method or consult our lab diamond guide.
