Custom Engagement Rings NYC

A Private Williamsburg Studio Experience

You don't need to know anything about diamonds to walk in here. If traditional jewelry stores have felt overwhelming or transactional, this space was created for you. Most couples who find us arrive feeling unsure where to start. That's completely normal here.

Who This Studio Is For

Some want calm guidance choosing the right ring from our curated collection. Others walk in with a sketch on the back of a napkin, a Pinterest board, or just a feeling they can't quite name yet. Both are perfect starting points. Every ring we make is handcrafted to order, never pulled off a shelf.

Haejin Jewelry is a woman-owned fine jewelry studio in Williamsburg, Brooklyn, designed for NYC couples who want a calm, private experience and an engagement ring made with ethical, lab-grown diamonds.

Haejin is for couples who:

  • Want calm, pressure-free guidance from a single dedicated jeweler
  • Care about ethical sourcing and lab-grown diamonds
  • Want a handmade ring with a story behind it, not something stamped out by a machine
  • Prefer a private studio over a crowded retail floor

We may not be right for you if:

  • You want a machine-made ring available for same-day pickup
  • You need the ring within 48 hours and cannot wait 3 to 4 weeks
  • You prefer a large retail showroom with hundreds of ready-made options on display

How Custom Engagement Rings Are Made

1
Free Consultation

A calm conversation where you don't need the right words. We guide you through style, budget, and priorities. Most consultations last 45 to 60 minutes.

2
Design Direction

We narrow choices thoughtfully so decisions feel clear. You'll see inspiration photos, metal samples, and diamond options side by side.

3
3D CAD Model

Every bespoke ring begins as a precise 3D model. You review proportions, setting height, band width, and every detail before anything is made. Unlimited revisions until it feels right.

4
Handmade. Never Machine-Made.

Your ring is crafted entirely by hand using 100% recycled gold and an IGI-certified lab-grown diamond. No mass production, no assembly line. Every stone is set by hand, every prong checked twice, every surface finished with intention.

5
Ready in 3 to 4 Weeks

We give you a clear timeline, not vague estimates. Rush orders available for 2-week turnaround.

Bespoke Engagement Rings in NYC

Most jewelers in New York City offer what they call custom rings. In practice, that usually means selecting a setting from a catalog and choosing a stone to drop into it. The design itself is predetermined.

Bespoke is different. A bespoke engagement ring begins as a conversation, not a catalog. There is no template. Sue works directly with you from a blank page, sketching proportions by hand before translating your vision into a precise 3D model. You approve every angle, every measurement, every detail before anything is made.

This is what it means to work with an engagement ring designer in NYC who treats your ring as a one-of-one piece. Whether you arrive with a Pinterest board, a family stone, or nothing more than a feeling, the process meets you where you are. The result is a custom diamond engagement ring that could not have been made for anyone else.

Why NYC Couples Choose Haejin

Private Studio

No foot traffic, no sales floor. Just you and your jeweler in a quiet Williamsburg studio. By appointment or walk-in.

Ethical Diamonds

IGI-certified lab-grown diamonds with the same brilliance, hardness, and fire as mined stones. 60 to 70% less expensive for identical quality.

True Bespoke, Handmade

Not template customization, not machine-stamped. Your ring is designed from a blank canvas, modeled in 3D CAD with unlimited revisions, and crafted entirely by hand.

Crafted in NYC, Never Outsourced

Your ring is crafted right here in New York City. Nothing is shipped overseas, nothing is outsourced. If you ever have a question, a resize, or need care for your ring, you come back to the same person who made it. No salesperson, no call center. Just Sue.

Custom Engagement Ring Pricing

Our custom engagement rings with IGI-certified lab-grown diamonds start from $1,450 including the setting and center stone.

The same ring with a natural diamond would cost $4,000 to $12,000 at traditional NYC jewelers.

No hidden fees. No markup surprises. Sue walks you through every cost before you commit.

We accept all major credit cards, PayPal, Shop Pay installments, and Venmo. 50% deposit to begin, balance on completion.

What Our Couples Say

★★★★★

I had no idea what I wanted but Sue helped guide and educate me. She encouraged me to take my time in my decision as it was a big one! I didn't see the final creation until I was proposed to and I was blown away. Truly exactly what I wanted. I am so happy to support a small business in my neighborhood.

Unlike other places I visited, it was obvious that Sue really cared about finding what was best for us, and not just trying to sell us the most expensive ring possible. If you go with Haejin you absolutely will not regret it and you will receive something better than you ever could've imagined.

She helped me create the ring of my dreams. Sue involved me in the whole process, so I got to see the stone in person before moving forward, and got a mockup of the design as it was being made. The result is unreal. Local, woman-owned, and realistic pricing...I can't say enough good things about Haejin Jewelry.

She guided me, explained all the different options, we iterated together to find something which my partner would like and then she manufactured our dream ring for us. Sue is incredibly warm and kind and I can only recommend anyone to go to her. My fiancée immediately said yes and she thinks the ring is "just perfect."

From the very beginning Sue made the entire experience feel so easy, thoughtful, and personal. She found the most incredible antique elongated cushion stone — truly the ring I had been searching for my whole life, even in my dreams!! I truly cannot recommend Haejin enough.

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.

Shea's underwater scuba diving proposal with Haejin Jewelry engagement ring

Shea proposed underwater with a ring from our studio. She said yes before they surfaced.

He presides over promises for a living.

Barry is a Brooklyn judge. When it came time to make a promise of his own, he walked into our Williamsburg studio. His fiancee knew exactly what she wanted. An emerald cut diamond she had been imagining for years. Over many visits, we refined every detail together until the ring in her mind became the ring on her hand.

The photo booth strip beside it is their story.

What the Industry Says

Our clients share their experiences above. Here is what wedding industry professionals and Brooklyn press have to say.

Wedding Industry Expert

"This is what shopping for a ring should feel like. Not a sales floor, but a conversation."

Lauren Ladouceur (@planwithlaur) is a NYC-based wedding content creator whose videos reach millions of viewers on TikTok and Instagram. Her work has been featured in The New York Times, The Wall Street Journal, People Magazine, and The Knot. After covering hundreds of weddings, she visited Haejin's Williamsburg studio and wrote about the experience in her 2026 engagement ring guide.

Brownstoner

"The space itself reflects why women choose to shop for engagement rings in Brooklyn instead of Manhattan: it is calm and simple. There is time to ask questions, time to think, and it feels more like a thoughtful conversation than a performance."

Brownstoner is Brooklyn's leading publication covering real estate, design, and neighborhood life. Their 2026 profile of Haejin Jewelry covered Sue Kim's journey from the diamond industry to founding an ethical studio in Williamsburg.

The Diamond District is still good for commodity purchases where you know exactly what you want. National brands are convenient and well-marketed. But for a ring that is genuinely yours, designed by a real person who will know your name five years from now, a private studio is a different category entirely.

What Most First-Time Buyers Get Wrong

Even couples who do their research can overlook a few things that matter more than they seem.

Choosing for the photo, not the hand. Tall, elaborate settings look stunning in close-ups but can snag on sweaters, bump against desks, and feel heavy on a hand that moves through a real life. The rings that get worn happily for decades tend to sit low and feel invisible.

Prioritizing size over cut. A smaller diamond with an excellent cut will look brighter and more alive than a larger stone with a mediocre one. Cut is what creates fire. We always recommend choosing cut first.

Forgetting the wedding band. Your engagement ring and wedding band need to sit together on the same finger. If the engagement ring has a wide or unusual profile, a standard band may not sit flush. We design both at the same time so they work as a pair.

Assuming bespoke is out of reach. Most couples who walk in expecting to spend $5,000 or more are surprised to learn that a fully custom ring with an IGI-certified lab-grown diamond starts from $1,450. The assumption that custom means expensive is the biggest barrier, and it is usually wrong.

Lab-Grown Diamonds: Same Stone, Different Origin

A lab-grown diamond is physically, chemically, and optically identical to a mined diamond. This is not marketing. It is the official position of the GIA (Gemological Institute of America) and the FTC. Both are pure carbon, both are graded on the same 4Cs scale, and both are certified by the same independent laboratories.

The difference is origin and price. A lab-grown diamond is created in a controlled environment in weeks rather than extracted from the earth over millennia. The result is a stone that costs 60 to 80 percent less than a mined diamond of identical specs. A 1.5-carat E VS2 lab-grown round brilliant that would cost $8,000 to $12,000 as a natural diamond costs $1,800 to $3,000 as lab-grown.

Every lab-grown diamond at Haejin comes with an IGI certification documenting carat weight, cut grade, color grade, clarity grade, and a unique serial number you can verify online. Every setting uses SCS-certified 100% recycled solid gold. Never plated, never hollow, never vermeil.

The question is not whether lab-grown diamonds are real. They are. The question is whether you want to spend $8,000 more for the same stone. Most NYC couples in 2026 are choosing to put that difference toward the wedding, the honeymoon, or their first apartment together.

"I do not see mined diamonds as the equivalent of wearing real fur, but I do think women today want choices that reflect their values."
Sue Kim, founder of Haejin Jewelry, in Brownstoner

Frequently Asked Questions

How much does a custom engagement ring cost in NYC?
Our custom engagement rings start from $1,450 with an IGI-certified lab-grown diamond and setting included. The equivalent ring with a natural diamond would cost $4,000 to $12,000 at traditional NYC jewelers. Sue provides transparent pricing during your free consultation with no obligation.
How long does it take to make a custom engagement ring?
Most custom rings are completed in 3 to 4 weeks from your initial consultation. This includes design, 3D CAD modeling, revisions, and handcrafting. Rush orders are available with a 2-week turnaround for an additional fee.
Do I need an appointment for a custom ring consultation?
Walk-ins are welcome during our open hours when availability allows. For a dedicated 45 to 60 minute session, we recommend booking a free consultation online. Either way, there is never any pressure or obligation.
What is a lab-grown diamond?
A lab-grown diamond has the same physical, chemical, and optical properties as a mined diamond. It is real carbon, real diamond, with identical brilliance, hardness, and fire. The only difference is origin. All our diamonds come with IGI certification documenting carat, cut, color, clarity, and a unique identification number.
Can I design my own engagement ring from scratch?
Yes. Every bespoke ring at Haejin starts with a blank canvas. You work directly with Sue to explore shapes, settings, metals, and stones. We create a 3D CAD model you approve before anything is made. Unlimited revisions are included.
What if my ring gets damaged over time?
Your ring is designed to be worn every day. That is what it is for. Over the years, it will collect the kind of wear that comes from a life fully lived: tiny scratches from carrying groceries, a prong that loosens after years of holding your hand against a steering wheel, a finish that softens with time. That is not damage. That is evidence that you wore it the way it was meant to be worn. Every ring from Haejin comes with a lifetime warranty. If anything ever needs attention, whether it is five years from now or twenty, bring it back to Sue. She will inspect it, repair it, and return it to you. Free of charge, no questions asked. The same person who made your ring is the person who will take care of it for the rest of your life. We are not in the business of selling you something and disappearing. We are in the business of making sure that what you wear from Haejin lasts as long as the promise it represents.
Where is Haejin Jewelry located?
Our private studio is at 123 Skillman Ave, Williamsburg, Brooklyn, NY 11211. We are a 5-minute walk from the Lorimer St station on the L train. Free street parking is available on Skillman Ave directly outside the studio.
Do you offer payment plans for engagement rings?
We accept all major credit cards, Apple Pay, PayPal, Shop Pay installments, and Venmo. A 50% deposit begins your custom design, with the balance due on completion. Shop Pay offers interest-free installment options.
What certifications do your diamonds have?
Every lab-grown diamond at Haejin comes with IGI (International Gemological Institute) certification. This independent report documents the diamond's carat weight, cut grade, color grade, clarity grade, and assigns a unique serial number that can be verified online.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. Both are pure carbon with the same hardness (10 on the Mohs scale), the same refractive index, and the same brilliance. The GIA, IGI, and FTC all classify lab-grown diamonds as real diamonds. The only difference is how and where they were formed. A gemologist cannot tell the difference without specialized equipment.
What is the best place to buy an engagement ring in NYC?
It depends on what kind of experience you want. The Diamond District on 47th Street has the largest selection of loose diamonds in the city, but the experience can feel high-pressure and transactional. National brands like Brilliant Earth and VRAI offer showrooms with lab-grown options. For a private, pressure-free custom design experience with a single dedicated jeweler, Haejin Jewelry in Williamsburg, Brooklyn offers free consultations, lab-grown diamonds, and true bespoke design starting from $1,450.
How do I design a custom engagement ring?
At Haejin Jewelry, the custom design process has five steps: (1) a free 45 to 60 minute consultation where we discuss your style, budget, and vision; (2) design direction where you see inspiration photos, metal samples, and diamond options; (3) a precise 3D CAD model with unlimited revisions; (4) handcrafting in recycled gold with an IGI-certified lab-grown diamond; and (5) delivery in 3 to 4 weeks. You work directly with Sue, the founder, from start to finish. No salesperson, no middleman.
Can I try on engagement rings before buying?
Absolutely. Our Williamsburg studio has sample settings, loose diamonds, and metal swatches available to try on during your consultation. Walk-ins are welcome during open hours, or you can book a private appointment for an uninterrupted session. Many couples find that seeing and feeling the rings in person changes their mind about what they thought they wanted. That is the whole point of the studio experience.
Do you make engagement rings for same-sex couples?
Yes. We welcome all couples and design rings for every love story. Many same-sex couples choose to design matching or complementary engagement rings together during a joint consultation. We have experience designing rings that work beautifully as pairs while reflecting each person's individual style. His and his, hers and hers, theirs and theirs.
Is it better to design a ring in Brooklyn or Manhattan?
Manhattan's Diamond District on 47th Street is built for commodity transactions: high volume, fast turnaround, competitive pricing on standard cuts. If you know exactly what you want and your priority is the lowest price per carat, the District serves that purpose well. Brooklyn studios like ours exist for a different reason. When you want to design something from a blank page, sit with one person who knows your name, and take your time without pressure, a private studio gives you the space that a busy sales floor cannot. Many of our clients visit the Diamond District first and then come to us. They are not looking for a better price. They are looking for a better experience.
What if I am visiting NYC and want a custom ring?
We work with couples visiting from across the country and internationally. Schedule your consultation early in your trip so we have time for measurements, design direction, and any follow-up questions. Your ring will be crafted after your visit and shipped to you in secure, insured packaging within 3 to 4 weeks. Many of our favorite engagement stories started with a couple visiting Brooklyn for the weekend and walking into our studio.
