I am absolutely thrilled with my experience at Diamond Registry. I have purchased many expensive pieces of jewelry, including large diamonds, for my ex-wife over the past 20 years. My recent purchase from Nissan and Shai Perla was by far the most pleasant, courteous, transparent and efficient. Never was I pressured or "sold." Shai took an incredible amount of time educating me and presented 6 different stones of similar cut, color and grade at different price points. After my 90 minute meeting with him, I checked his price points against the Rapp Report, Blue Nile, James Allen and Rittani and the prices were all slightly less than his competitors PLUS I got the benefit of actually seeing and examining the stones with a loop and comparing them to the GIA certificates for each stone. In researching my purchase, I spent countless hours with many diamond dealers on 47th Street and on websites like Blue Nile, James Allen and Rittani. I happened to chance upon Diamond Registry's website and filled out the online form describing what I was seeking. Nissan Perla called me directly from Hong Kong that night and spent considerable time trying to understand what I was seeking and then had his son Shai totally prepared for my appointment the next day in their offices (not retail store or kiosk). Later that day, I did a little research on the Perla's and was surprised to find that Nissan is world famous for being the jeweler to numerous celebrities and dignitaries. Being humble, Nissan and Shai never once mentioned their clout in the trade to impress me. If you are shopping for a serious diamond, this is the only place you need to visit. read more
