A modern approach to diamonds
The Clear Choice for Responsible Diamonds.
What is a Lab Grown Diamond?
A lab-grown diamond is a gem that is identical in chemical composition to a mined diamond. However, lab-created diamonds are grown in a laboratory environment.
In contrast, natural diamonds are mined from the earth. Lab-grown diamonds are “real” diamonds, but they are grown in a sustainable manner.
There are two distinct manufacturing processes used to grow diamonds in a lab: HPHT and CVD.
HPHT (High Pressure High Temperature) is the older of the two processes and has been around since the 1950s. In HPHT, a small amount of graphite is subjected to extreme temperatures and pressures.
The HPHT method replicates the extreme heat and pressure conditions found deep inside the earth that cause natural diamonds to form.
The second and more modern method is termed CVD (Chemical Vapor Deposition). This is a vacuum deposition method that is often used in the semiconductor industry to produce thin films.
The diamond CVD technique was first investigated over 30 years ago. However, it is only within the last decade that the technology improved to the point where high-quality diamond can be created.
In CVD, a thin slice of diamond, commonly referred to as a seed, is placed in a sealed chamber and heated to a very high temperature. After the chamber is heated, a carbon-rich gas mixture is introduced into the chamber, and those gases are ionized into plasma. The chemistry created in the plasma along with the high sample temperature results in growth of high-quality diamond.
Diamonds are most often recognized as a gem stone, but they are also used for hundreds of industrial processes, some of which our rough growing partner ‘Clarity’ is exploring. The work of perfecting lab-grown diamond growing will continue to be an important part of Clarity Diamond’s Research and Developments’ future.
It’s R&D team continues to innovate the growing process, as well as the equipment they use to grow diamonds. To date, very few lab-grown diamond producers can grow diamonds to the same size and quality that Clarity consistently produces.
We’re pretty excited about that because it enables us to offer larger lab-created diamonds in larger sizes. Lab-grown diamonds are a fantastic example of advancing technology and scientific ingenuity. If you’re into innovation, a lab-grown diamond is certainly symbolic.
How Brian Gavin Lab Grown Diamonds Are Made:
We use lab grown rough from the world’s leading grower our partner Clarity from Austin, Texas USA. They use the CVD (chemical vapor deposition) method of growing lab-created diamonds.
The growing process begins with a seed that is essentially, a thin wafer of diamond material. The diamond seed is sealed in a vacuum chamber and heated to 900° Celsius and inundated with carbon rich gasses.
There are various patents pending that describe Clarity's processes enabling them to grow the material in a single cycle. Those processes support better transparency, so light can pass through the material unhindered.
In that case, when cut to the Brian Gavin patented process to maximize light performance there is no other combination in the world like this, it is truly unique.
Another very important factor is that there are no HPHT post growth processes after the crystal is grown, unlike other producers.
We also offer lab grown diamonds grown with the HPHT method.
Creating a responsible business requires a lot of focus and effort. Responsibility encompasses a vast array of social, human rights, and environmental issues. We are looking at every aspect of our business and asking questions like:
- Where did this come from?
- Who produced it?
- Did they have healthy working conditions?
- Were they treated with respect and dignity?
- Did creating it cause any environmental damage?
If there’s one thing we’ve learned, it’s that responsibility is a journey, and not a destination.
We value living right. That means respecting our employees and treating them well. It also means taking care of the environment, being an honest and transparent business partner, and becoming a trusted supplier to our clients. In short, we think doing good is good business.
