Lab-Grown Diamonds


Lab-grown diamonds, also known as man-made or synthetic diamonds, are diamonds that are created in a laboratory setting using advanced technological processes. They are chemically, physically, and optically identical to mined diamonds. The process of creating lab-grown diamonds typically involves using high pressure and high temperature (HPHT) or chemical vapor deposition (CVD) methods to replicate the natural diamond-forming process. These diamonds can be made in a fraction of the time it takes for a mined diamond to form, and can be produced in a controlled and predictable environment. Because they are made in a laboratory, lab-grown diamonds can offer a higher quality at a less expensive price than mined diamonds of similar quality. Additionally, the production of lab-grown diamonds has a smaller carbon footprint than traditional diamond mining, making them a more sustainable option for consumers who are concerned about the environmental impact of their purchases.

What is GIA?

The Gemological Institute of America (GIA) is an independent and nonprofit organization that developed the 4C’s and the International Diamond Grading System as we know it. GIA screens every gemstone to identify synthetics, simulants and known treatments. Expert gemologists examine each diamond under controlled lighting and viewing conditions, in order to provide the most rigorous assessments of a diamond's 4C’s. 

We will walk you through every aspect of diamond grading and the 4C’s in person so you can select the right diamond for you!
