This week’s stack is a study in contrasts – and complements. Black and white, yin and yang, silver and gold. We start with a thick band from TAP by Todd Pownell; its diamonds are bright points of light emerging from the darkened 18k white gold like a constellation in the night sky. A Polly Wales band has scattered deep, dark black sapphires peeking out from within gleaming 18k yellow gold. Atop that rests a Lauren Wolf three-diamond ring, with its salt and pepper diamonds dappled with black carbon inclusions. Finally, a gradient diamond ring by Scosha, embracing the full spectrum of light and darkness within one gracefully arched band.
