Laboratory-grown diamonds go by many names, often called lab diamonds, lab created or synthetic diamonds. While the names might have slight variations, they all point to a diamond that has been created in a controlled environment, such as a laboratory, rather than naturally in the earth’s surface.
Are laboratory-grown diamonds actual diamonds?
Yes! Laboratory-grown diamonds are chemically identical to natural, earth mined diamonds. They are indistinguishable to natural diamonds without expensive laboratory equipment.
Most laboratory-grown diamonds are created using a high pressure, high temperature (HPHT) method which mimics the natural environment in the earth’s surface that creates natural diamonds. This process works by taking a diamond seed (a natural diamond) and exposing it to extreme pressure (roughly equivalent to the same pressure you would find if you balanced an airplane on your finger) and temperatures as high as 1600 degrees Celsius.
Why should I buy a laboratory-grown diamond?
Sustainability is one of the main reasons why someone might choose to purchase a laboratory-grown diamond vs a natural, earth mined diamond. While creating laboratory-grown diamonds requires a large amount of energy, it is often seen as a cleaner, more sustainable way of acquiring a diamond.
The other main reason is cost. Laboratory-grown diamonds can be more than 30% cheaper than their natural, earth mined equivalent, meaning that you can often get a much larger, high-quality laboratory-grown diamond for the same price as its earth mined cousin.
