Sublime Sparkle

Double Take

These bicolored tourmalines were supposed to be earrings, but the designer Cora Sheibani instead incorporated them into a gorgeously graphic cuff. ($14,650, kultia.com)

In the Round

My favorite series from H. Stern’s new Iris collection is Shelter, with its welded gold balls. Each piece has a unique shape. (Ring, $5,200, and earrings, $5,600, H. Stern, New York, 212.655.3910)

Give a Hoot

I love the playfulness of these earrings by the Athens designer Nikos Koulis. They’re inspired by owls, which, according to Greek mythology, bestow wisdom upon the wearer. (Blackened gold, emerald, tsavorite, and diamond, $19,505, nikoskoulis.gr)

Well Built

The husband-and-wife team behind Roule & Company takes an architectural approach to design, evident in these cool bangles. (From left: Diamond, $32,500; ruby, $39,500; emerald, $42,500; Bergdorf Goodman, New York, 212.753.7300)

Young Turk

Graphic designer–turned–jeweler Pinar Oner’s debut collection pays homage to her native Istanbul: Her Byzantine-esque rings are hand-enameled using a technique she learned from master craftsmen at the Grand Bazaar. (From left: Gold and diamond, $16,000 and $15,000, pinaronerdesign.com)
