Golden Lock. Hidden Heart.

Handcrafted in Brazil, this lock pendant is filled with thoughtful details—from delicate screw accents and a sparkling cubic zirconia keyhole to engraved hearts hidden on the back, like a secret love note worn close to your heart.

A lightweight brass base is first coated with 24K gold, then finished with generous layers of 22K and 18K gold, producing a luminous finish rated between 18K–24K.

Water-resistant, nickel-free, and hypoallergenic, it's designed to retain its beauty through everyday wear..
