        Certified Diamonds & Gemstones sold me a pair of 7 carat diamond custom and handmade earrings. I couldn't be more thrilled and I have enjoyed wearing them to many black-tie events.

        Thank you CDGI for your tremendous assistance and for offering these exquisite diamond earrings at such a great value.

        Rough Diamond Purchase

        My most recent diamond rough purchase from Certified Diamonds & Gemstones went very well. They sold me the rough diamonds and then had their expert diamond cutters create a finished product for me. The rough diamonds were cut to the highest specifications and I was very pleased with the result.

        I will continue to purchase all of my rough diamonds from CDGI - as I have for over a decade.

        I had a pleasant experience with Certified Diamonds & Gemstones. I recently purchased a 5ct. diamond engagement ring from them and when I proposed to my fiancé, she was speechless. I will never forget the look on her face; it was priceless.



        I plan to continue doing business with Certified for all of my future jewelry needs.



        Thank you Certified,



        Kevin

        I am ecstatic about my recent purchase from Certified Diamonds & Gemstones. I just bought an 8 ct. diamond ring from them and it is simply stunning.



        I was especially satisfied with the level of professionalism and the value that I received. CDGI shipped my diamond ring to me and the process went very smoothly.



        I will continue to purchase diamonds from CDGI and I will refer my friends and family to them as well.

        I am a jewelry designer and I have been a loyal CDGI client for over a decade. CDGI has always provided excellent customer service and has continuously delivered premium merchandise at dealer pricing. In addition, I am out of the U.S. and shipping always goes very smoothly.



        Thanks CDGI, for always being a part of my businesses success.
