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.

Frequently Asked Questions | Haejin Jewelry Brooklyn

Are your diamonds certified and conflict-free?

Yes. Every Haejin lab-grown diamond is IGI or GIA certified and responsibly grown by trusted laboratories. Our Brooklyn jewelry studio is deeply committed to ethical sourcing and sustainability, ensuring each diamond embodies transparency, integrity, and modern luxury without the environmental or social impact of traditional mining.

Do you use real gold or gold-plated jewelry?

We use only solid, SCS-Certified 100% recycled gold in every design. Haejin Jewelry does not sell gold-plated jewelry. Our engagement rings and wedding bands are always solid gold, while our bracelets and fine jewelry are crafted only in solid or gold-filled materials, never plated or vermeil. Each piece is hand-inspected, polished, and quality-checked in our Williamsburg studio for lasting brilliance.

Why Are Our Prices Lower?

At Haejin Jewelry, our prices reflect honesty, not markup.

We’re not a corporation. We’re a small, Brooklyn-based studio run by people who believe luxury should have a conscience. We don’t answer to investors, we don’t inflate prices for showrooms, and we’ll never hide behind the illusion of “exclusivity” to justify a higher tag.

Every piece you see is the result of direct, hands-on craftsmanship, not a retail chain or a middleman. Every day, our founder Sue drives two hours each way to our Williamsburg studio so she can personally oversee each design and final inspection. She makes that drive by choice, because to her, integrity is not something you delegate; it is something you show up for.

While large jewelry companies spend millions on glossy magazine ads, celebrity endorsements, and corporate campaigns, we choose a different path. We invest that same energy and cost into the things that truly matter: better materials, better craftsmanship, and better ethics. Every dollar goes toward your piece, not a billboard or an influencer contract.

We use only GIA and IGI-certified lab-grown diamonds and SCS-certified 100% recycled gold. Our studio runs on transparency and purpose, not overhead and profit margins.

Our lower prices are not a discount; they are a declaration. They prove that fine jewelry made with integrity and world-class quality should never be out of reach. We built this company not to enrich ourselves, but to show that beauty, meaning, and fairness can exist in perfect balance.

Learn how this philosophy shapes everything we do in our Economics of Lab-Grown Diamonds blog, a transparent look into how we keep luxury honest, sustainable, and accessible for everyone.
