Hamilton Jewelers opened its fifth location, in Red Bank, N.J., in a historic three-story building constructed in 1878. Occupying over 5,000 square feet of selling space on two levels, the first floor boasts a designer gallery, a diamond boutique, and a timepiece arena. More than 600 guests attended a premiere opening gala held in December.
