Gary was fantastic and took his time to take us through our recent engagement ring purchase. He ensured that we understood exactly what we had purchased and explained all of the critical items to look out for with our diamond. We are so happy we found him and went here for the grading and appraisal and would recommend to everyone.
Gary is definitely an expert, but he is also clearly passionate about his work. I came for an insurance appraisal of an inherited diamond ring, but I also left with a wealth of knowledge about the different cuts, clarities, styles, and types of diamonds that exist out there. My appointment felt like a lesson as well as an appraisal, and I mean that in the best way. I would absolutely recommend this service!
