Lab-grown diamonds are a widespread choice of mined diamonds. They are created in a lab under controlled conditions, using advanced technology to replicate the natural diamond formation process. Lab-grown diamonds have the same chemical and physical properties as mined diamonds and are less expensive. 

Contrary to natural diamonds, created in the Earth's crust over centuries or even millennia under extreme pressure and heat conditions, the LGDs are created in labs using the CVD and HPHT techniques. A crystal with a distinctive shape can be created in less than a month.

A seed, or a piece of another diamond, is the foundation upon which the LGD is built. The HPHT process imitates the high-pressure, high-temperature circumstances that develop into a natural diamond deep within the Earth. To create an LGD, the graphite and seed carbons are subjected to high pressures and temperatures (1,500 degrees Celsius). 

The HPHT method is primarily used to produce LGDs in China. In India, the CVD approach is more widely used. The seed is heated to 800 degrees in an enclosed space that contains molecules of carbon-rich gas, such as methane, during the chemical process known as CVD. These gas molecules are disassembled into atoms of hydrogen and carbon, which are deposited on the seed and give it the shape of a square, tabular diamond crystal. For the crystal to take on a coloured appearance, this process also needs heat or radiation.

The naked eye cannot distinguish natural diamonds and lab-grown diamonds. Nitrogen is present in natural diamonds, but nitrogen is absent from lab-grown diamonds. One of the indicators gemologists look for when determining whether a diamond is lab-grown or natural is this one. 

Natural diamonds are formed over millions of years beneath the pressure of the Earth's crust, after which they are mined, cut, and polished. The exact trials are run on a lab-grown diamond but in a different environment. The method used to produce a Lab Grown Diamond drastically reduces the growth time from millions of decades to a few months. Afterwards, the lab diamond is also polished and cut.

How Good Are Diamonds Grown in a Lab?

In general, the response is affirmative. Accredited gemological labs refer to and grade Lab Grown and authentic Diamonds by the varying degrees of internal "inclusions" compared to fingerprints. The "naked eye" can see inclusions in Lab-grown or natural diamonds with a lower clarity grade. When deciding whether a diamond is fantastic, very good, average, or poor, the cut and colour are also crucial factors.

The cost of the Lab Grown Diamonds.

The rarity of natural diamonds contributes to their high cost. There are no guarantees of what will come from the Earth, and they rely on intricate and expensive mining operations.  Natural stones are believed to be in limited supply on Earth, and each one is formed under specific conditions, so the qualities used to grade gemstones will also be unique.

Other factors affecting the price of diamonds include the time and effort required for extracting and polishing the diamonds and the market's dubious history of control and strategic origins. Because they are not subject to the same supply chains as natural diamonds, lab diamonds will typically cost less than natural diamonds—up to 50% less than a stone of comparable grade.
