BBB Review (3/18/2018)
Working with Ron was an absolute pleasure. I'll shamelessly admit to being a total amateur concerning diamonds. I was hesitant of shipping my diamond to #1 Diamond Source without being able to visit the shop in person. But I did research on the business and Ron and every detail I found was consistent with who he said he was and what he said he does. And so I sent him my diamond. Ron was informative and helpful during the process. He was also honest, which is always a relief. From my limited knowledge, I knew of a few techniques of improving a diamond's appearance, and when I inquired about one such technique, he laughingly said he'd accept my money but that he recommended NOT carrying out that technique. From my experience, he is a down to earth individual who knows his stuff. Saying I was thoroughly impressed with the final product would be an understatement. I could not get over how the color and clarity had improved. This was a fantastic investment.

Hi Ron,
The re-cut diamond just arrived and it looks magnificent. Thank you for the wonderful service and quality of workmanship. I will definitely recommend you to friends and others in the trade. I get a fair number of inquiries from people looking for diamond repair work, and will send them all your way since I only cut colored stones and not diamonds.

Hi Ron,
The diamonds arrived safely. Please post this on your wall of fame. You and your team did a fantastic job re-cutting my diamonds! They are beautiful full modern-brilliants that will make any woman smile (and me too, since I will be the one selling the stones!). Your team was exceptionally courteous and I intend to be a loyal lifelong customer.
Thanks Again,
