N.J. Diamonds is proud to introduce our custom jewelry designer, Custom by Z. ‘Custom By Z’ is what we came up with. The one person in our store who made these pieces of jewelry has a first name that starts with Z, so we chose Custom By Z. Customizing a piece of jewelry isn’t easy. Taking someone’s vision and turning it into a tangible piece of jewelry takes many hours of work.
