Congratulations Shaun & Julie on your Engagement!

Congratulations Shaun & Julie on your Engagement! I am truly excited for the two of you and honored to have been able to help you select the 0.731 carat, G-color,VS-2 clarity, round brilliant ideal cut diamond from the Brian Gavin Diamond Blue Collection.  The picture to the left is an actual photograph of your engagement ring, the eight pointed star pattern visible in the picture represents the contrast created by the camera lens reflecting off of the eight pavilion main facets located on the pavilion (lower half) of the diamond.

True Beauty which is Quite Rare

This diamond was produced by some of the finest diamond cutters in the world and exhibits superior Light Return and Visual Performance which is the sparkle factor of the diamond which was graded as having an overall cut rating of AGS Ideal-0 by the AGS Laboratory on their Platinum Light Performance grading platform.  It is estimated that fewer than 1% of all the round brilliant cut diamonds produced in the average year are cut precisely enough to receive an overall cut grade of AGS Ideal-0.

Proportions and Plotting Diagram from Brian Gavin Blue, AGS#104063639042The picture to the left is the proportions diagram and plotting diagram from the AGS diamond grading report, the proportions grade of this diamond is AGS Ideal-0 which means that the measurements of this diamond fall within a very precise set of parameters.  This translates to a higher amount of light return in terms of the volume of light being reflected through the diamond and back up towards the viewer (that’s you).  In terms of light return, the two most important sections of the diamond are the crown angle which measures 34.8 degrees and the pavilion angle which measures 40.8 degrees which is smack dab in the center of the spectrum for the zero ideal cut rating!The plotting diagram indicates that the primary inclusions within the diamond responsible for the VS-2 clarity grade are crystals and pinpoints, which are merely tiny diamond crystals that were trapped within the larger diamond crystal as it formed… baby diamonds if you will.


Crystal Clear VS-2 Clarity

Clarity Photograph for Brian Gavin Blue, AGS#104063639042This is a photograph of your diamond as seen through a gem scope using 10x magnification which is intended to make it easier to see the inclusions within the diamond.  The clarity grade of this diamond is VS-2 which stands for Very Slightly Included.  As you can see, the inclusions are not readily visible using this magnification, but you should be able to find them using a 10x diamond grading loupe with a little practice.  There is also an inscription located along the girdle edge of the diamond which consists of the logo for Brian Gavin Blue and 104063639042 which is the number from the corresponding AGS Diamond Quality Document.


This Puppy will Light Up Your Life!

ASET Scope Image for Brian Gavin, AGS#104063639042Everybody likes to think that their diamond is the most beautiful in the world, but yours is one of the few diamonds in the world that has been graded as having AGS Ideal-0 Light Performance using the Angular Spectrum Evaluation Tool (ASET) which is proprietary technology designed by the American Gemological Society Laboratory to demonstrate where the diamond is gathering light from in a hemispheric shaped room which is similar to the earth’s atmosphere.  The ASET scans the diamond from 244 vantage points, each color represents a different region of light in the room as it reflects back at you.


Maximizing Light Return by Minimizing Light Leakage

Ideal Scope for Brian Gavin Blue, AGS#104063639042The image to the right shows your diamond as seen through an Ideal Scope which is designed to show where the diamond is leaking light… all diamonds leak light, but some leak less than others. The reddish pink areas of the images represent light which is entering the diamond and being reflected back up towards the viewer, the darker arrows represent light which is being blocked from entering the diamond by the viewer’s head (or in this case the camera lens) and the white areas around the edge of the diamond which is minimal leakage, typical of a zero ideal cut diamond of this cut quality.


Every Puppy Needs a Name:

Blue Fluorescent Diamond, Brian Gavin Blue, AGS#104063639042And a good one for this diamond might be “Little Boy Blue” because he will glow this beautiful neon blue color when placed under black light… this phenomena is similar to the Phosphorescence that can be seen in ocean waves as they crash upon the beach at night when certain animals and plant life are present.  I’m a big fan of blue fluorescent diamonds, to the extent that practically every diamond which I’ve ever worn personally has exhibited medium to strong blue fluorescence. Your diamond exhibits strong blue fluorescence when viewed under black light, you should definitely take a trip to an aquarium shop because this is an absolutely beautiful phenomena!

Shaun and Julie, I want to thank you once again for allowing me to help you select the diamond for your engagement ring! I wish both of you a long and wonderful life together and look forward to hearing from you from time to time… Feel free to download any of the images on this page and/or to link to it via any social media platforms you use.
