Lab Grown Diamond Engagement Rings in New York

Ships duty-paid · nothing owed at delivery

New York has seen most of America's diamonds — it is not easily impressed.

Each Signora ring is made to order in our family's workshop in Surat — where roughly ninety percent of the world's diamonds are cut and polished — and travels duty-paid to your door in about fourteen days, from Brooklyn to Buffalo. No middlemen, no showroom markup.

A New York story

The Block Where America's Diamonds Change Hands

New York's diamond trade began on Maiden Lane in the late 1700s and moved uptown in the 1920s, when purpose-built exchanges rose on West 47th Street. Dealers arriving from Antwerp and Amsterdam in the 1940s made the block between Fifth and Sixth Avenues what it remains: the single stretch of pavement through which roughly nine of every ten diamonds entering America still pass.

Nine of ten diamonds entering America cross one block; nine of ten worldwide cross Surat.

Surat holds a statistic of its own: roughly ninety percent of the world's diamonds are cut and polished on its wheels. Our family has been in that trade for three generations — founder Himmat Mangukiya joined at nineteen — and has run its own polishing unit there since 2006. Every Signora ring is made to order in Surat and delivered duty-paid to your door in about fourteen days.

One street taught America how to judge a diamond. One city taught our family how to make one.

Duty-paid delivery to New York

Your ring ships to New York fully duty-paid (DDP). All import duties and customs charges are calculated and paid by us before dispatch, so there is nothing to pay at your door — no surprise fees, no customs paperwork, no courier holding your ring hostage. Crafting takes about 7 business days in our Surat workshop, followed by roughly 7 days of insured, tracked transit to any New York address. That's around two weeks from order to knock on the door. Shipping is free on orders over $500 — which covers nearly every engagement ring we make. Every lab grown diamond arrives with its IGI certificate, and every moissanite with its GRA certificate.

Getting your ring size right in New York

Because every Signora ring is made to order to your exact size, we can't resize it after delivery — so getting the size right up front matters. The easiest route: walk into any trusted local jeweler in New York and ask to be measured. It takes two minutes and virtually every jeweler does it free. Prefer to sort it from your couch? Book a free 20–30 minute consultation at calendly.com/signorajewels and we'll walk you through sizing discreetly — useful if the proposal is still a secret. And if something isn't right, standard designs carry a 30-day return window, with return shipping covered by us. Fully custom pieces are made to your specification and are non-returnable. And every ring is backed for a lifetime.

Beyond the engagement ring

Lab Grown Diamond Jewelry, Delivered Across New York

The Engagement Gallery is where most New York stories begin — but it isn’t where our workshop stops. The same cutters and setters make lab grown diamond rings for every occasion, wedding bands for him and her, diamond tennis bracelets, necklaces and pendant sets, solid gold chains, and lab grown diamond earrings — each made to order in solid 9K, 14K, or 18K gold or platinum, never plated.

Whether you’re searching for lab grown diamonds in New York for a proposal, a moissanite solitaire on a sensible budget, or colored gemstone jewelry that doesn’t follow the crowd, the promise stays the same: IGI- and GRA-certified stones, about two weeks door to door, and nothing owed at delivery — in New York City, Buffalo, Rochester, and Albany, and every town between.

Engagement Ring FAQs — New York

How long does delivery to New York take?

About 7 business days to craft your ring in our workshop, then roughly 7 days of insured transit to your New York address — around two weeks in total. Fully custom designs take a little longer.

Will I pay customs or import duty in New York?

No. We ship duty-paid (DDP) to the entire United States. Duties are settled by us before your ring leaves the workshop, so the price you see at checkout is the final price. You owe nothing at delivery.

Can I return a ring from New York?

Yes — standard designs can be returned within 30 days, and we cover the return shipping. Fully custom, made-to-spec pieces are non-returnable.

Are the diamonds certified?

Every lab grown diamond is IGI-certified and every moissanite is GRA-certified. The certificate ships with your ring.

What metals can I choose?

Sterling silver 925; yellow, white, and rose gold in 9K, 14K, and 18K; and platinum Pt950. Solid metal only — never plated or vermeil. Our white gold is palladium-based, nickel-free, and rhodium-finished, making it a strong choice for sensitive skin.

Do you deliver jewelry other than engagement rings to New York?

Yes — wedding bands, tennis bracelets, necklaces, pendants, chains, and earrings all ship to New York the same way: made to order in Surat, delivered duty-paid in about two weeks, with IGI certificates for lab grown diamonds and GRA certificates for moissanite.

Style notes

Engagement Ring Styles in New York

Manhattan · Brooklyn

The low-profile bezel

A bezel-set oval or round sits flush to the finger — a stone that rides the subway, types all day, and still reads unmistakably considered across a dinner table.

Brooklyn · Albany

Vintage lines, new stones

Milgrain edges, marquise accents, and hidden halos nod to the estate cases of 47th Street — antique in spirit, set with a lab grown stone that is anything but.

Buffalo · Rochester

Classics with conviction

Upstate leans traditional and means it: a round brilliant on a cathedral band in 14K yellow gold, the kind of ring that looks inherited the day it arrives.

Whatever the setting, paying the maker rather than the middleman is a deeply New York satisfaction.
