5 out of 5 stars

I have given Brian Gavin Diamonds five stars as it not only meets but far surpasses all criteria I set for a diamond jeweler which I can confidently recommend.

This is a diamond jeweler that can truly be worthy of the title of fine jeweler. There are a lot of diamond vendors offering "ideal cut diamonds" and "super ideal cut diamonds", however there is only one Brian Gavin; and as a fifth generation diamond cutter, Brian Gavin has the experience and expertise to create diamonds that deliver an incredible volume of light return and sparkle factor, we're talking about a level of visual performance that is second to none! Although Brian Gavin did not invent the Hearts and Arrows cut diamond, he has been a major influence in developing and promoting the "Hearts and arrows diamond grading standards" that are used by the upper echelon of the diamond industry. The stones sold by Brian Gavin Diamonds take about four times longer to polish and produce than your average "Excellent cut" diamond. All their diamonds are AGS graded. Each in house diamond is displayed in 360° and is shown in various ways including how it shows up under an ASET.
