What is a Lab Diamond?
Lab Grown or Cultured  Diamonds are real diamonds. Lab Diamonds and Natural Diamonds are the same, both chemically and visually. A “Lab Diamond” is just like a Natural Diamond, except instead of growing in the Earth, they grow in a lab. There is no visual difference in Lab Created Diamonds vs Natural Diamonds. They sparkle the same, have the same types of color and clarity, and can come in the same sizes and shapes. Likewise, Lab Grown Diamonds are just as hard as Natural Diamonds.

What are the differences between Lab Diamonds vs Natural Diamonds?
Although there is no difference in appearance between high quality Natural Diamonds vs Lab Diamonds, there are big differences in cost, value, rarity, and sustainability.

Lab diamond versus mined diamond

High Quality Lab Diamonds and Natural Diamonds look exactly the same.
Lower clarity Lab Diamonds have a few inclusions that do not occur in Natural diamonds.
There is no difference in look between high quality Lab Diamonds vs Natural Diamonds. Both Natural and Lab Grown Diamonds can be colorless or near colorless. They both can also be a variety of candy colors. Likewise, both Lab Diamonds and Natural Diamonds come in all standard shapes such as round, princess, oval, marquise, pear, cushion, radiant, emerald, and asscher. The sparkle and brilliance of Lab and Natural Diamonds are the same. High Quality stones are identical in look. Lower clarity lab diamonds (those where inclusions are visible to the naked eye) may have different inclusions than their natural counterparts. This is discussed in more detail below.

Lab created diamonds are physically, optically, and chemically the same as a mined diamond. This means that they are made of the same material, have the same chemical components, and look the same as a mined diamond. Lab grown diamonds are just as hard and scratch resistant as mined diamonds and are cut with the same precision mined diamonds are. In fact, each one comes with a laser inscription and a report.

Not only do lab created diamonds look and wear the same way as a mined diamond, they cost less than a mined diamond. You can get a 30% larger lab diamond for the same price as a mined diamond!

The one difference in appearance between a lab created diamond and a mined diamond is the color. When earth mined diamonds get lower in color, they get warmer, or more yellow. Lab created diamonds have a pinkish brown undertone instead that some people don’t care for. However, the laboratories growing these diamonds are constantly changing their “recipe” and experimenting to achieve a greater percentage of colorless diamonds.

Just like in mined diamonds, color varies in lab created diamonds. However, clarity is usually on the higher side of the scale, typically SI (slightly included, yet eye clean) or better. They usually are not lower than that due to the way they’re grown.
