LONDON — There’s a new designer duo in the jewelry world: none other than Brangelina.

Brad Pitt and Angelina Jolie are breaking into high-end jewelry design with Asprey via a capsule collection of gold jewelry and silver accessories called The Protector — and inspired by the snake.

The limited edition collection, which was conceived and designed by Pitt and Jolie, has been in the works for more than a year, and will go on sale at Asprey stores in London, New York, Beverly Hills, Tokyo and Dubai later this week, according to Asprey officials.

Prices start at $525 for a silver baby spoon with a curving, serpent-shaped handle, and all net proceeds from sales will go to Education Partnership for Children of Conflict, which was cofounded by Jolie in 2006. The charity raises awareness and funds to educate child victims of war, conflict and natural disasters.

Jolie and Pitt declined to talk about their collection for Asprey, opting instead to discuss the aims of the charity in an e-mailed quote attributed to Jolie: “These are the children who most need a safe place to learn, a place to heal, a place to learn reconciliation, a place to build a better future and a place — to just be children. Yet the education for these children is often forgotten. Tens of millions of children and adolescents in conflict are not in school.”

An Asprey spokeswoman declined to comment on the collection beyond confirming the facts, and would not say whether celebrity collaborations would be a future strategy for the brand.

The jewelry-loving Jolie has worn Asprey — and other names including Lorraine Schwartz and Mikimoto — on the red carpet. Pitt, who has a passion for architecture and design, in the past has created pieces for the Italian jeweler Damiani. Both Jolie and Pitt have also commissioned pieces privately from Asprey.

So why the serpent theme? When she was pregnant with their daughter Shiloh, Jolie was given a ring — not from Asprey — in the shape of a snake. Since then she’s considered the reptile a talisman and protector of her family.
