Laser inscription:
Most lab-grown diamonds have a laser inscription on the girdle, which is the widest part of the diamond. The inscription will include the initials of the lab that created the diamond, as well as a unique identification number.
High-pressure, high-temperature (HPHT)
In the HPHT process, a small diamond seed is placed in a chamber with a carbon source, such as graphite. The chamber is then heated to extremely high temperatures (up to 2,000 degrees Fahrenheit) and pressures (up to 150,000 pounds per square inch). The carbon source is then converted into diamond, which forms around the diamond seed.
Ethical:
Lab-grown diamonds are not mined, which means that they do not contribute to the environmental and human rights concerns associated with diamond mining.
Lab grown diamonds look exactly like natural diamonds. They have the same physical and chemical properties, including the same hardness, durability, and sparkle. The only difference between lab grown diamonds and natural diamonds is the way they are created. Natural diamonds are formed over millions of years deep within the Earth, while lab grown diamonds are created in a laboratory in a matter of weeks or months.
There are two main types of lab-grown diamonds: high-pressure, high-temperature (HPHT) diamonds and chemical vapor deposition (CVD) diamonds. HPHT diamonds are grown under extreme heat and pressure, while CVD diamonds are grown by depositing carbon atoms onto a substrate.
Lab-grown diamonds, also known as synthetic, cultivated, or man-made diamonds, have their roots in the mid-20th century. The first commercially successful attempts at creating these diamonds in a laboratory setting began in the 1950s. The General Electric Company, through a research project led by H. Tracy Hall, developed the first reproducible process for creating diamonds in the lab in 1954. The process involved a high pressure, high temperature (HPHT) method, which mimicked the natural conditions under which diamonds are formed deep within the Earth.
Diamond Foundry: This company is based in California and uses a process called chemical vapour deposition (CVD) to grow diamonds. It is one of the most well-known lab-grown diamond brands, and its diamonds are known for their high quality.
Yes, lab-grown diamonds and lab created diamonds are the same thing.
Jewellery: Lab-grown diamonds are often used in jewellery, such as engagement rings, necklaces, and earrings. They are a popular choice for those who are looking for an ethical and environmentally friendly diamond.
No. Most diamonds are still mined, but lab-grown diamonds are becoming more popular. In 2021, only about 5% of the global diamond supply was lab-grown. However, the demand for lab-grown diamonds is growing, and it is expected that they will account for a larger share of the market in the future.
