Lab-Grown Diamond Engagement Rings in Brooklyn, NY
"You already know. You've known for a while now. That quiet certainty when you look at them across a restaurant table, on the subway platform at Lorimer St, walking home through the Williamsburg Bridge. The ring is just the last piece of a decision your body already made."
Haejin Jewelry. A woman-owned studio in Williamsburg, Brooklyn. Lab-grown diamonds. Recycled gold. Made for the moment you've been rehearsing in your head.
You Care About Where Things Come From. So Do We.
The Diamond
Every diamond we set was grown in a lab, atom by atom. Same carbon. Same fire. Same hardness. Zero mining. You're not compromising. You're choosing the version that doesn't leave a hole in the earth.
The Gold
100% recycled solid gold. Not plated. Not hollow. Not new-mined. The metal in your ring already existed. We just gave it a second life and a better story.
The Studio
A woman-owned workshop on Skillman Avenue in Williamsburg. Not a chain. Not a showroom with fluorescent lights and commission breath. A place where Sue sits with you and sketches what you're imagining.

How to Design Your Engagement Ring Near Brooklyn
Whether you start online or visit us in person, every ring at Haejin Jewelry is made to order. There is no inventory to browse, no display case to lean over. You design something that exists nowhere else in the world. Here's how it works.
1. Explore
Start with our online Ring Builder to browse settings, shapes, and metals. Or use our Custom 3D Design tool to build something from scratch. You can also skip straight to a consultation if you'd rather talk it through in person.
2. Consult
Book a private appointment at our Williamsburg studio, 10 minutes from Brooklyn. Sue will sit with you, learn what you're drawn to, and guide you through diamonds, metals, and settings at your pace. Most visits are 30 to 45 minutes. No pressure, no upselling. Bring a mood board or bring nothing at all.
3. Create
Once you've chosen your design, we build it. For custom rings, that means 3D CAD modeling, revisions until every detail is right, and handcrafted production in recycled gold with an IGI-certified lab-grown diamond. Your ring is finished within a few weeks and shipped with free insured delivery. 60-day returns if anything isn't perfect.
The Same Diamond. A Different Decision.
A lab-grown diamond isn't a simulated diamond. It's a real diamond. Same carbon lattice, same Mohs 10 hardness, same fire under restaurant lighting. The only difference is origin. One came out of the earth. Yours was grown in a chamber that recreates the conditions 100 miles below the surface. The result is indistinguishable. The cost isn't.
Why Brooklyn Couples Choose Haejin Jewelry
There are a lot of places to buy an engagement ring in New York. Department stores with fluorescent lighting. Chain jewelers where the salesperson works on commission. Online retailers where you never see the ring until it arrives in a box. Haejin Jewelry is none of those things.
We are a woman-owned, by-appointment studio in Williamsburg, Brooklyn. Every ring is made to order with lab-grown diamonds and 100% recycled gold. Our founder, Sue Kim, works directly with every client. There is no sales team, no call center, no middleman. When you email us, Sue responds. When you visit, Sue is the one sitting across from you.
Couples from Brooklyn and neighborhoods across Brooklyn, Queens, and Long Island come to our studio because they want something different. They want to understand exactly what they're buying. They want to see the diamond before it's set. They want a ring that reflects their relationship, not a template from a catalog.
We specialize in lab-grown diamond engagement rings because we believe the science is settled. A lab-grown diamond is a real diamond. It has the same carbon crystal structure, the same hardness, the same optical properties as a mined stone. The difference is that ours are grown in a controlled environment over a few weeks instead of extracted from the earth over billions of years. Every stone we sell is certified by IGI and comes with a full grading report.
Our prices start at $1,450 for a complete engagement ring with a lab-grown diamond. That same ring with a mined diamond would cost $3,500 to $8,000 at a traditional jeweler. We show you the price upfront. There are no hidden fees, no "call for pricing" games, and no pressure to spend more than you planned.
Questions from Brooklyn Couples
What Our Clients Say
"Personal care from an expert jeweler. Sue reached out to me directly, helped me design the ring, helped me pick out a diamond, and negotiated on my behalf. I got a great deal for the size and quality of diamond and it's so beautiful. Honestly couldn't be happier."
"When we walked into this studio it felt cozy and not corporate. We decided to design a custom engagement ring and I ended up changing my mind more than once. She was surprisingly patient about it all and never made me feel difficult. That meant a lot. The ring feels like something we chose together and took time on."
"Shopping for an engagement ring was honestly overwhelming. We visited a bunch of big name stores, but they all felt the same. Sue wasn't trying to sell me anything. She was patient, clear, and genuinely informative. She explained how to choose the right diamond, what lab grown diamonds really mean, and why their gold is ethically sourced. There was no pressure at all."
