Haejin Jewelry

Haejin Jewelry is a custom lab grown diamond engagement ring studio in Williamsburg, Brooklyn. We design made to order engagement rings and fine jewelry around the diamond you choose, so every piece is built for one couple and one story.

Custom is what we do best. Start from a classic solitaire, a hidden halo, a three stone, or a design entirely your own, then shape the setting, metal, and diamond with us until it is exactly right. Prefer to begin online? Our ring builder lets you design your own engagement ring from anywhere, and we guide you through every step.

Lab grown diamonds are the heart of our work. They are real diamonds, chemically and optically identical to mined stones, grown in a lab rather than the earth. That means a larger, brighter, more brilliant diamond for your budget, and an ethical, conflict free choice you can feel good about for a lifetime.

Couples across Brooklyn, Manhattan, Queens, and the greater NYC area visit our studio for a calm, pressure free appointment to see lab grown diamonds in person, compare settings, and design together. Whether you arrive with a clear vision or a blank page, we make the process personal and unhurried.

As a woman owned studio, we treat every couple the way we would want to be treated. Each ring includes a lifetime warranty and complimentary cleaning for life, so your ring is cared for long after the proposal.
