I had an excellent experience dealing with J.S. Diamonds. The entire process was straightforward and easy. Communication was clear and prompt throughout. Most importantly, I felt I could trust them completely, and they offered the fairest pricing I found after doing my research. I highly recommend J.S. Diamonds. Great service all around.

SIMPLY FANTASTIC! Sal & Jessica (and Lola!) provided the best customer service. In addition to being extremely knowledgeable about the market and the business they conduct, this outstanding team were more than fair when it came to buying the items I brought with me! They took the time to explain to me in a very easy, friendly way how they test for certain materials/metals, the market value of such metals, and pretty much everything I needed to know. I HIGHLY RECOMMEND you come and visit their business right in the heart of Rockefeller Center!

I scheduled an appointment with them, and as soon as I got there I was taken care of. All the staff is very friendly. Regarding location, amazing building and office in great condition.
