JB Diamonds & Fine Jewelry Inc. is located in the San Miguel Plaza on San Miguel Drive in Newport Beach, just down the road from Fashion Island and next to the Edwards Cinemas complex. It specializes in diamonds and high-end jewelry at great prices. It designs its own pieces and can custom-design one-of-a-kind pieces for customers using 3-D computer modeling and other tools to construct the pieces from scratch. All the work is done in house and JB gets its diamonds directly from the diamond cutters so it prides itself on the value of the service for the price. The Web site is a great resource to understand the differences between different cuts of diamonds and features a list of the different types of pieces JB designs and carries. JB also offers jewelry and watch appraisals and repairs, as well as engraving and enameling services.
