Founded in 2012 with the iconic recasting of a carabiner lock into precious metals, our collection has grown into a universe of mechanism-inspired, “hard-working” jewelry—convertible rings, clasps, charms, and more—ranging from $100 to $300,000. Handmade in New York’s Diamond District, our pieces are designed to bring joy, be worn endlessly, and redefine what’s “precious” with individuality.

Founder, Marla, brings a rebellious spirit to everything they do—from vending machine sales and museum exhibits to gifting thousands of Heartlocks to single moms. In 2024, she received the prestigious Gem Award for Jewelry Design.
