Bardot Ring in silver with amethyst, worn

40th Birthday Jewelry

Forty earns the signature piece. 40th birthday jewelry should be one thing with real weight, chosen properly: a signet with her initials, a solid bangle, a hand-cut stone or enamel she'll be asked about. Everything here is made by hand in our London workshop in solid silver or gold, and engraved on the inside if she'd like it. Pick the kind of thing, and we'll show you five, and the one we'd choose. Prices are on every piece.

Engraving

Add a date, or her initials

Almost everything here can be engraved by hand in our workshop: the date, her initials, the thing you always say to her. Hidden on the inside of a ring or bangle, or on the back of a heart or charm. From $10 an engraving. Engraved pieces can't be returned, so if you're unsure of the size, order it plain and we'll engrave it together afterwards.

We bought a silver skull bracelet for my mom's birthday, who has been wearing Stephen Einhorn jewelry for years. She was thrilled once again, and the team arranged for it to be made extra quickly in the workshop to make sure it arrived in time.

My second time buying from Stephen Einhorn. Faultless, efficient and very friendly service. And most importantly, my wife loves the piece of jewelry as much as the last one!
