GN Diamond has been in existence for over 35 years with offices in Israel and Philadelphia. We are a direct cutter and manufacturer of diamonds and fine diamond jewelry. Below are some photos of our office facilities in Philadelphia - we recently underwent a cosmetic reconstruction to expand the office to better serve the needs of our staff as well as our customers. We have state of the art equipment right here in our 8,000 sq. foot Philadelphia headquarters, with experienced jewelers and gemologists on hand, working to create unique designs and ensure that your finished requests are completed in a timely fashion. We're open seven days a week for your convenience - give us a call at: 1-800-724-8810
