About AGS and GIA Graded Diamonds

Almost any diamond will look impressive under the bright spotlights of a jewelry store, but a rare few have the unique combination of precise cut, shape, and angles to hold their brilliance in more natural lighting situations. Beyond the basic “4 Cs” (carat, color, clarity, cut/shape) used to determine a diamond’s overall quality, there is another level of excellence that involves the symmetry and reflective quality of a diamond’s cut, and potentially enhances all of the 4 Cs. This reflective quality determines how well a diamond “performs,” in other words, how well it reflects light under all lighting conditions and situations.

About Brian Gavin Diamonds

On our Web site, you’ll find loose diamonds and diamond jewelry set with the finest performing diamonds available in the world, as well as information for your personal diamond education. Our diamonds are graded by both the AGS (American Gem Society) and the GIA (Gemological Institute of America), organizations known for their strict grading standards. Whether personally designed and overseen by master cutter, Brian Gavin, for his Signature Line, or hand-selected by Brian from trusted suppliers for his Select Line, our diamonds offer you a range of choices for your needs. Our diamonds are separated roughly into two main categories: Brian Gavin Signature and Online Inventory.

What Makes Brian Gavin Signature Diamonds Special

For the discriminating buyer seeking the finest cut and polished diamonds available, Brian Gavin Signature diamonds exceed all expectations. Each displays a unique brilliance and fire that reveals the distinct beauty and personality of the stone, and gives voice to the inner essence of the diamond through its contrast, brightness and scintillation.

Brian Gavin Signature diamonds go beyond the ideal diamond standard in terms of consistency, precision and cutting design to achieve the level of “super ideal” in visual balance and performance under any lighting condition. These signature diamonds are skillfully shaped to ideal mathematical proportions, using a complex formula in which every facet is placed at the precise angle to create the perfect balance between maximum brilliance (return of light to the eye) and the optimum scattering of light, or "fire" (this is the prism effect that separates white light into its spectral colors). Over the past 12 years, Gavin has produced more than 12,500 of these super ideal diamonds. Today they are prized and widely appreciated around the world for their outstanding beauty.

Our Virtual Inventory

Brian also carefully analyzes and selects diamonds from a variety of local and international suppliers to offer to our customers. These select stones have been cut with excellent precision and come from “conflict free” areas of the world (areas where the local population isn’t exploited in the mining of the stones). Diamonds and jewelry that meet Brian’s strict “Select” quality standards exhibit outstanding cut, color and clarity, as demonstrated by their light performance. And, for the diamond buyer, they represent the optimum balance between performance and value.
