Artificial diamonds, also known as lab-grown diamonds or synthetic diamonds, are a popular alternative to natural diamonds. However, many people use the terms "artificial" and "synthetic" interchangeably, which can lead to confusion about the differences between the two. In this article, we will explore the key differences between artificial diamonds and synthetic diamonds.
Firstly, it's important to understand that both artificial diamonds and synthetic diamonds are created in a laboratory setting, rather than being mined from the earth like natural diamonds. However, the processes used to create these diamonds differ in important ways.
Artificial diamonds are created using two main methods: high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD). In the HPHT method, a small diamond seed is placed in a chamber with carbon and subjected to high pressure and high temperature to encourage the growth of a larger diamond crystal around the seed. In the CVD method, a gas mixture containing carbon is heated to produce a plasma, which causes the carbon atoms to settle on a substrate and form a diamond layer.
Synthetic diamonds, on the other hand, are created using the HPHT method, but with a key difference. Instead of using a diamond seed, synthetic diamonds are created by subjecting a carbon source - such as graphite - to high pressure and high temperature to encourage the growth of a diamond crystal.lab cut diamonds. This means that synthetic diamonds are not technically "grown" around a seed like artificial diamonds are.
Another key difference between artificial diamonds and synthetic diamonds is their color. Artificial diamonds can be created in a variety of colors using different chemical additives during the growth process. Synthetic diamonds, on the other hand, are typically colorless or near-colorless, although they can be treated with irradiation or other processes to create different colors.
In terms of quality, both artificial diamonds and synthetic diamonds can be of high quality and have similar characteristics to natural diamonds. However, synthetic diamonds are generally considered to be of higher quality than artificial diamonds, as they are created using a purer source of carbon and are not subject to as many impurities during the growth process.
Finally, there is a difference in price between artificial diamonds and synthetic diamonds. Synthetic diamonds are generally more expensive than artificial diamonds, as they are considered to be of higher quality and are created using a more complex and expensive process.
In conclusion, while artificial diamonds and synthetic diamonds share many similarities, there are several key differences between the two. From the methods used to create them to their color, quality, and price, understanding these differences can help consumers make informed decisions about which type of diamond is right for them.
