The Gavin Effect® Now In Lab Grown

A breakthrough in light optimization in diamonds.

A break through in raw material

Light is everything when it comes to diamonds. The way the light catches a diamond during a pivot or a gesture. The hypnotic movement of light as it dazzles the eye—captivating the viewer and drawing them close.

The unique patented processes in material and Light performance is what separates Brian Gavin® Lab Grown from other Lab grown diamonds this dazzling light performance is due to a patent cutting technique, which is the result of years of extensive experimentation and diamond research which was vetted by the American Gem Society Lab. You can be assured a Gavin Effect® in LAB grown diamonds meets our strictest and most exacting quality requirements.

To achieve our strictest and most exacting light performance requirements for the Gavin Effect® cut, every diamond in the Brian Gavin® Lab Grown collection, we select the finest possible lab grown diamond material that is grown in a single cycle by our partner Clarity in Austin TX USA . Then we follow a meticulous and proprietary process to optimize secondary angles, symmetry, and reflective potential. We then inspect each diamond to ensure that it meets the pinnacle of our demanding light performance standards for the Gavin Effect®.

The result is a lab grown diamond that has Impeccable Performance®, Exacting PrecisionTM and Incomparable Beauty®. and you're guaranteed to find it in the full product range of Brian Gavin®.


Brian Gavin Lab grown material is mostly colorless and there is NO POST GROWING HPHT ENHANCEMENT TO CHANGE THE COLOR


The clarity of the material is mostly VS2 and better


The cut that creates a Brian Gavin® Lab Grown delivers super light performance. And are cut according to the patent to maximize the light return sparkle and scintillation


A Brian Gavin® Lab Grown will present pristine and symmetrical hearts and arrows, a feature that is synonymous with the name Brian Gavin.


The Angular Spectrum Evaluation Tool®, or ASET, was developed by AGS to demonstrate, in red, green, and blue colors, the light performance of a diamond (how it handles and returns light to our eyes). See the following examples Both ASET images achieve the 0 for light performance grade. However, the one on the left displays “Low-intensity light zones" beneath the table. While the one on the right has been optimized for Gavin Effect®. All diamonds in Brian Gavin® collections will have the most exacting ASET image possible showing premium light performance

The angles

Brian Gavin® Lab Grown diamonds feature pristine hearts and arrows and are crafted to evoke Gavin Effect® maximizing light performance (US Patent number: 10405618). Most diamond crafters focus on the primary angles and stop there. We take it a step further, purposefully optimizing the ancillary angles of each Brian Gavin® Lab Grown. The result? Extremelight performance so you get the most vibrant reflective qualities and the most hypnotizing sparkle imaginable.

The quality

We offer unparalleled quality in every Brian Gavin® Lab Grown. How do we know? We know because we use the world-leading lab in light performance—AGSL—to grade the color, clarity, and light performance of each stone. That’s also why we can proudly say that the quality is assured not only by Brian Gavin, but also by the AGSL.
