"This is the second time I have worked with Jonathan. He is very professional and pays promptly. I trusted him enough to send him my jewelry prior to purchase. With all the fraud going on trust is very important today. Thanks for that Jonathan." - Bebra Lynch
"This place was GREAT! Jonathan exceeded expectations -- he knows diamonds, has all of the tools and connections that are top notch! Evaluated my diamond, tested my diamond and shared the entire process with me. His approach, process and transparency is exactly what the GIA Institute said I should experience and cautioned me about the traps of NY Diamond Market. I did not get lucky with Jonathan with others recommending him to me it was an easy, pleasurable and rewarding experience. Simple, honest and easy -- at a minimum you owe yourself to give him a call if you are buying or selling a diamond -- he is a cut above! Highly recommend. - Steve Martucci"
