Are lab-grown / lab-created diamonds real diamonds?

Yes, lab-grown diamonds are real diamonds. Lab-created diamonds are as real as natural diamonds since they share similar physical and chemical properties.

What's the difference between lab-grown and earth-grown diamonds?

The differences between lab-grown and earth-grown (natural) diamonds are not visible to the naked eye. While natural diamonds have trace amounts of nitrogen, lab-grown diamonds contain no nitrogen. Also, the pressure of the earth’s crust over millions of years creates natural diamonds before they’re mined, cut, and polished. The same process is simulated in a laboratory to create lab-grown diamonds in just a few months.

How do I find high-quality lab-grown diamonds?

Find high-quality lab-grown diamonds by confirming certification by GCAL, IGI, or any lab offering specific color and clarity grades. Pay attention to the 4Cs: carat, cut, clarity, and color. They affect the look of every diamond.

Do lab-grown diamonds deteriorate over time?

Because they have the same physical properties as their natural counterparts, they do not discolor, fade, or cloud. It will look the same in a million years as it does when you receive it.

Why should I buy lab-grown diamonds over earth-grown diamonds?

You should buy lab-grown diamonds over earth-grown diamonds since they’re eco-friendly; they don’t cause air and water pollution. They’re also ethically sourced as they’re not linked to conflicts and human rights abuses.

How are lab-grown diamonds made?

Lab-grown diamonds are made by subjecting carbon to high pressure and temperature in a controlled environment.

What are some facts about lab-grown diamonds?

Facts about lab-grown diamonds: they are eco-friendly, ethically sourced, and identical in every way to earth-grown diamonds. They are also sustainable since they don’t have supply constraints. Lab-grown diamonds must be certified by independent labs to verify their authenticity and quality.

Why aren't lab-grown diamonds more mainstream?

Lab-grown diamonds aren’t more mainstream because there has been a lot of misinformation by diamond mining companies about lab-grown diamonds, saying that they’re not real because they’re not mined.

How expensive are lab-grown diamonds vs earth-grown ("real") diamonds?

Earth-grown diamonds are more expensive than lab-grown diamonds. The cost of lab-created diamonds is 10 – 50% less than mined diamonds of similar quality and size. However, with both, the price of lab-grown diamonds depends on the cut, color, and clarity ratings, just like it does with natural diamonds.

Are lab-grown or earth-grown diamonds illegal anywhere?

Lab-grown diamonds are not illegal anywhere. But earth-grown diamonds, particularly conflict diamonds, are illegal everywhere. However, the official statement is that conflict diamonds have been eradicated from the global marketplace.
