Minimalism at its most luxurious — this 14k yellow gold bar necklace makes a statement through simplicity, with prong-set round diamonds catching the light along a sleek horizontal bar pendant. The clean, architectural design is the kind of piece that works with everything from a crisp white shirt to an evening gown, and the rhodium polish gives it an extra layer of brilliance. Worn on an 18-inch cable chain with a lobster clasp, it's effortlessly refined.
