A ring stack can bring so much personality to a look, and this curated threesome from By Pariah is particularly compelling. Here, you have a chunky donut-shaped band done in recycled 14-karat gold, a thinner one rimmed with lab-grown diamonds, and a hand-carved ring of red jasper, which is said to promote feelings of security and stability. Wear them all together, two at a time, or spread across multiple fingers—the options are endless.
