What are lab-grown diamonds?

Lab-grown diamonds are diamonds that were grown by scientists in a lab. They share the same chemical makeup as natural diamonds, and are optically identical. The biggest differences between them are how they’re made, and how rare they are.

How are lab-grown diamonds made?

 

There are a few methods used to grow lab-grown diamonds. Typically, lab-grown diamonds start with a tiny lab grown diamond, like a seed. The seeds are placed in a chamber called a plasma reactor (in the case of CVD synthesis) or a large mechanical press (if manufactured by HPHT). Then, depending on the technology used, some combination of heat, pressure and a carbon source are used to make the crystals grow, layer by layer.

Where are Lightbox diamonds manufactured?

LAB-GROWN DIAMONDS VS. "REAL" DIAMONDS

Lab-grown diamonds are 100% diamonds. They share the same chemical makeup, optical properties and hardness as natural diamonds. The only things that set them apart is how they’re manufactured and our ability to keep making many more of them into the future. By contrast all the natural diamonds that will ever exist on the earth have already been created by nature.

Can you tell the difference between lab-grown diamonds and real diamonds?

Are lab-grown diamonds worth less than natural diamonds?

Lab-grown diamonds vs. Diamond simulant

While they may look similar, diamond simulants (like cubic zirconia) are chemically not diamonds at all. They’re completely different gems and materials. On the other hand, lab-grown diamonds are chemically the same as natural diamonds, but their creation process is sped up by science.

What is a simulated diamond?

Diamond simulants and lab-grown diamonds often get mixed up, but they’re completely different. A diamond simulant is not a diamond at all, because the chemical properties are completely different. They can be made out of anything from glass to cubic zirconia. While they may look similar at first, diamond simulants aren’t as hard and don’t have the same optical properties as diamonds, so they’ll show signs of wear and won’t be as sparkly.

Lab-grown diamonds vs. Cubic zirconia

Cubic zirconia was created to be a less expensive alternative to diamonds. It’s chemically completely different, not as hard and lacks the same sparkle. It’s also not considered a gemstone because it can’t be found in nature. It’s made from powdered zirconium and zirconium dioxide, melted together and formed into a stone.

Lab-grown diamonds vs. Moissanite

Moissanite is a completely different gem, that tends to be less expensive than a diamond. It started out as a naturally occurring mineral, but natural supply wasn’t enough to make even the smallest pieces of jewelry. Scientists then found a way to replicate it in a lab to make it commercially available. While it might look like diamond it’s a much lower grade on color and hardness.
