Learn More About Lab‑Grown Diamonds
Lab‑grown diamonds are diamonds that have been grown in a controlled laboratory setting. They are physically and optically the same as mined diamonds, made of the same chemical composition, and feature the same properties, including their brilliant appearance, hardness and durability. Lab‑grown diamonds are virtually indistinguishable from mined diamonds.
Just like mined diamonds, lab‑grown diamonds are made of carbon atoms in a specific arrangement that results in the formation of a diamond crystal, which is ultimately fashioned into a very hard and brilliant gem.
Lab‑grown diamonds begin with a very thin lab-grown diamond plate (a seed diamond), which is placed in a chamber with carbon material. From there, one method of making lab‑grown diamonds uses intense heat and pressure, which allows the carbon material to bond and grow, layer by layer.
Another method uses a plasma reactor chamber to turn carbon-rich gases into plasma, which then bonds to the diamond plate layer by layer.
In short, lab‑grown diamonds can give you a higher quality diamond (think color and clarity) at a lower price. This is possible because lab‑grown diamonds are manufactured via a high‑tech process that is highly controlled compared to how the Earth produces diamonds (that's the higher quality) and they can be made in larger quantities than can be found in nature (that's the lower cost).
