If you’re going to go to all the trouble of making jewelry, you might as well go over the top. That seems to be the thinking behind a new jewelry collaboration between London jewelry designer Dominic Jones and Lady Amanda Harlech, who’s known mostly as Karl Lagerfeld’s number-one muse after she was John Galliano’s number-one muse.

Harlot & Bones, apparently a play on their names, takes its cues from Edwardian mourning jewelry and vintage heirlooms. Its 13 pieces include a “Poison” signet ring in onyx, a black rhodium locket pendant, beetle wing-motif pendants, and gold-plated locket cuffs. The signature piece — as shown in a campaign image shot by Nick Knight and featuring Amanda Harlech’s daughter, Tallulah, as a kind of art-nouveau nymphet — is a perfume-bottle necklace inlaid with turquoise stones.

€236 – €1,424 at Colette, Liberty, Net-a-Porter.com, Corso Como, Showstudio. Additionally, a student of the writings of Henry James, Harlech has written a poem accompanying each piece.
