What Makes Lab-Grown Diamonds Different?

Lab-grown diamonds share the same chemical, optical, and physical properties as mined diamonds. The difference lies in how they are created. Each diamond is cultivated in a controlled environment that replicates the earth’s natural conditions, resulting in a stone identical in beauty, brilliance, and durability but created responsibly with care for the planet.

Why Choose Haejin Jewelry in Williamsburg


At Haejin Jewelry, every engagement ring and wedding band is designed and finished with complete transparency, ethical sourcing, and respect for craftsmanship.

Every piece is created using responsibly sourced materials from trusted U.S. partners and completed with final inspection and quality control in our Williamsburg studio.

We use only solid, SCS-Certified 100% recycled gold and conflict-free lab-grown diamonds so each piece embodies honesty, sustainability, and timeless design.

Our bracelets, necklaces, and fine jewelry are never plated and are made only in solid or gold-filled materials, reflecting our commitment to lasting quality and integrity.

Our Clients and Community

We are proud to serve Brooklyn and New York City couples who value authenticity, sustainability, and connection. Every purchase supports a community built on kindness, creativity, and responsible luxury. Haejin Jewelry represents more than fine craftsmanship; it represents a commitment to ethical beauty and modern love rooted in Brooklyn.

Design Your Own Engagement Ring

Start by choosing a setting, then select the lab-grown diamond that fits your style and budget — and your ring is made to order. Every piece is hand-set and carefully inspected in our Williamsburg, Brooklyn, NYC studio using 100% recycled solid gold (never gold-plated or gold-filled).

Our engagement ring settings come in a range of styles — solitaire, three-stone, halo, and hidden-halo — each available in 10K, 14K, and 18K white, yellow, and rose gold, as well as platinum. You choose the center stone shape and size that works for you: round, oval, cushion, emerald, pear, and more. Pair any setting with a lab-grown diamond to get the same brilliance, hardness, and fire as a mined stone at a fraction of the price. Every stone is conflict-free.

Use our sizing tools to find your ideal carat weight and ring size before you finalize. For a walkthrough of the two-step process, read our design instructions . Prefer to work with a designer from a blank canvas? Our bespoke custom design service lets you create something that doesn’t exist yet — we’d be honored to help. For in-person guidance, contact us or visit our Brooklyn studio.
