You thought you knew your way around a compass.

Until you saw Rebecca Luong’s perfect circles. The local architectural designer created her Thinknow line of curvy jewelry using a laser cutter and mat board.

The deep black and glinting gray paper baubles are playful (they’re made out of scraps from Seattle frame shops) and elegant (pair with an over-the-top ball gown), highbrow and lowbrow from clasp to chain.

The new five-piece collection, Cape Olohana, looks like a whole mess of bubbles in profile, with one curve overlapping the next. Earrings are interlocking paper rings and sterling silver hooks, dangling rings show off a little mother-of-pearl, and everything is handmade in a sustainable fashion.

Without sending style back to the drafting table.
