What is a Lab Grown Diamond?

Lab-grown diamonds, also known or cultivated diamonds, embody the zenith of technological innovation and craftsmanship in the gem industry. These diamonds are not mere replicas but masterpieces that harmonize the physical, chemical, and optical characteristics of natural diamonds, cultivated meticulously in controlled laboratory settings.

The creation of lab-grown diamonds hinges on two predominant methodologies:

Chemical Vapor Deposition (CVD):

This technique employs a diamond seed positioned within a chamber infused with a rich carbon-gas mixture. The subsequent ionization of gases dismantles molecular bonds, facilitating the deposition of pure carbon onto the seed. This meticulous process fosters the crystallization of carbon, gradually crafting a diamond over several weeks, showcasing not only an improved transparency but also a heightened colorlessness and an unparalleled brightness.

High Pressure High Temperature (HPHT):

Mimicking the formidable conditions deep within Earth where natural diamonds forge, this method transforms a carbon source, typically graphite, into a crystalline diamond structure, courtesy of extreme temperatures and pressures and the presence of a metal catalyst.



Each piece in our Brian Gavin by Clarity Diamond™ collection is defined by three core principles:

Exceptional Quality, Environmental Responsibility, and Proudly American Grown. Allow us to take you through the unique journey that transforms an exclusive lab-grown diamond into a masterpiece of sparkle and brilliance.

At the heart of the Brian Gavin by Clarity Diamond™ lineage is an undeniable aspect of exceptional quality. Cut to our pateneted process of maximizing light performance these diamonds are sculpted to perfection, revealing an exquisite beauty that resonates even to the naked eye. Every facet works synergistically to capture and radiate light in a manner that redefines the brilliance associated with lab-grown diamonds.

Experience the SURE SPARKLE® emanating from our premium selection that features 3EX hearts and arrows rounds along with premium cut fancies, epitomizing the pinnacle of craftsmanship and elegance. Crafted through a patented single growth cycle CVD process*, these diamonds embody a natural aesthetic and an uninterrupted growth trajectory, devoid of visible growth lines. The inherent color and the absence of post-growth enhancements render each Brian Gavin by Clarity Diamond™ truly unparalleled and unique in its league.

In our pursuit of excellence, responsibility stands as a pivotal pillar. At the Clarity facility, relentless efforts are directed towards diminishing our environmental footprint and advancing towards a carbon-neutral status. The process reverberates with a commitment to the well-being of both humans and the environment, marked by prudent management of energy, water, chemicals, and waste.

By channeling close to 50% carbon-free energy, sourced predominantly from wind and complemented by solar and hydro-electric inputs, we are steadfast on our journey towards achieving a 100% carbon-free operation. It is a conscious endeavor that epitomizes responsibility, bridging luxury with sustainability.
