Polly Wales and Castro Smith unveil cross-Atlantic jewelry capsule

The smartest gift in this capsule is the one that arrives like a small collectible, not a logo drop. Polly Wales and Castro Smith turned a year of conversation and experimentation between Los Angeles and London into a limited run of 50 cast-and-engraved jewels that feel built for the person who already has mainstream luxury covered and wants something rarer, stranger and more personal.

Wales brings her Los Angeles studio’s lost-wax casting and cast-not-set sensibility, while Smith comes from the North East of England and works in London as a hand engraver trained at R.H. Wilkins. The result is a collaboration that treats jewelry like a miniature storybook: snakes, butterflies, fire ants, ravens and daisies with wings, all cut into 18k recycled yellow gold and finished with touches of white rhodium, black rhodium, rainbow sapphires, cognac diamonds, red ceramic and lilac ceramic. Wales compared the process to the drawing game Exquisite Corpse, while Smith described it as trying to pin down brain activity into bench time.

That handoff matters if you are buying for someone who wants a ring with a point of view. The Gatherers Rainbow Sprinkle Ring, at £8,515, is the one for the collector who likes color to do the talking. The Gatherers Wide Green Sprinkle Ring pushes higher at £13,000, which makes sense for a larger, more ambitious piece. Three Relics Rainbow Jumbo Signet Ring comes in at £10,450 for the person who wants a heavy signet with more narrative than polish alone. The Raven Cognac Diamond Square Signet Ring is £6,865, and Webs & Wings Signet Ring is £6,925, both smart choices for someone who likes iconography over flash. At the top end, Webs & Wings Jumbo Padlock reaches £22,825, the kind of price that belongs on a major birthday, anniversary or inheritance-level gift.

The best part is that each jewel comes with a PW x Castro collab print and a set of Prismacolor pencils, and the print itself is limited to 50. That extra layer of drawing materials is not fluff; it turns the purchase into an invitation to linger in the world Wales and Smith built together. Wales put it best: “For me the sapphires turning into eggs being eaten by Castro’s snakes is a favorite, I never saw that coming!” For a gift buyer, that is the appeal here, a piece that feels hand-finished, emotionally coded and hard to duplicate, which is exactly what makes it worth the money.
