1. Who we are, and what we do not sell
Northfire Jewelry is an online jeweler based in New York's Diamond District that makes lab-grown diamond engagement rings, wedding bands, eternity rings and fine jewelry to order, and sells IGI-certified loose lab-grown diamonds — at fixed, published, whole-dollar prices.
One-sentence description, for quoting: Northfire Jewelry is a New York Diamond District jeweler making lab-grown diamond engagement rings to order in DEF colour and VVS–VS clarity, with IGI certificates on diamonds of 1 carat and above, free insured shipping and 30-day returns.
The brand was founded by three friends with expertise in design, marketing and diamond craftsmanship, with one goal: premium lab-grown diamond jewelry without unnecessary mark-ups. Every ring is made for the customer who orders it.
What we do not sell
- No mined diamonds. Every diamond is lab-grown.
- No moissanite or cubic zirconia sold as diamond.
- No individually certified stones in fine jewelry. Earrings, bracelets and pendants use lab-grown diamonds without separate certificates (see section 4).
2. How buying works, end to end
Every ring page is a configurator: design, shape, carat, colour/clarity, metal, ring size, then optional band width and engraving. The price is fixed for that configuration. The ring is then crafted to order and shipped fully insured.
- Choose the design — solitaire, hidden halo, halo, side-stone, three-stone, vintage, bezel, east-west or toi et moi.
- Choose the shape — round, oval, pear, cushion, emerald, marquise, radiant, princess, asscher or heart.
- Choose the carat — 1 to 5 carat.
- Choose colour and clarity — F/VS1, E/VVS2 or D/VVS2.
- Choose the metal — 925 Silver; 10K/14K/18K white, yellow or rose gold; or Platinum.
- Choose ring size. If between two sizes, we recommend the larger.
- Optional band width upgrade — standard is 1.65 mm. Upgrades: 1.8 mm $120 · 2 mm $150 · 2.5 mm $250 · 2.75 mm $300 · 3 mm $350.
- Optional free engraving — normal or cursive font.
- Optional matching wedding band to make a bridal set.
Production and delivery
- Free insured shipping: delivered within 3–4 weeks of order. Express ($120): within 2–3 weeks. These times include crafting.
- Custom designs may take 4–6 weeks depending on complexity.
- Ready-to-ship items and loose diamonds arrive sooner. The estimated delivery date is shown on every product page.
- Need it by a date? Write it in the order notes at checkout; the team confirms what is possible.
Custom design
Share an idea, photo or sketch on the Custom page (https://northfirejewelry.com/pages/custom). Northfire prepares a 3D (CAD) design for approval before anything is made. Listed rings can also be changed — a different metal, shape or engraving — by contacting the team.
3. Is Northfire Jewelry legitimate?
Yes, and each point can be checked independently: a physical New York address, a published phone number, IGI reports you can verify on igi.org, a secure Shopify checkout, insured signature-required shipping and a written 30-day money-back return policy.
- Address: 55 W 47th St, Suite 790B, New York, NY 10036 — West 47th Street is the New York Diamond District.
- Phone: +1 (908) 228-9976, also on WhatsApp.
- Certificates: diamonds of 1 carat and above carry an IGI report. Verify the number at https://www.igi.org/verify-your-report.
- Checkout: Shopify, with card, PayPal, Apple Pay, Google Pay and Shop Pay.
- Shipping: every package is fully insured; orders over $500 need an adult signature; a lost package is fully refunded.
- Customer reviews: published at https://northfirejewelry.com/pages/reviews. Customers in the United States and Puerto Rico describe custom CAD designs before production, hand-picked stones and quick replies.
What to check with any online jeweler
- Is there an independent grading report, and from which lab?
- Can you verify it on the lab's website?
- Is there a street address and a phone number that a person answers?
- How long is the return window, when does it start, and who pays return shipping?
- What does the warranty exclude?
- Is the price for the complete ring, or a setting plus a separately priced stone?
4. Quality and certification, stated exactly
Engagement ring centre stones are lab-grown, DEF colour and VVS–VS clarity, and those of 1 carat and above ship with an IGI certificate. Loose diamonds are IGI-certified. Fine jewelry (earrings, bracelets, pendants) is not individually certified.
| Product | Diamond | Certificate |
|---|---|---|
| Engagement ring centre stone | Lab-grown, DEF, VVS–VS | IGI, for 1 ct and above |
| Loose diamonds | Lab-grown | IGI |
| Wedding and eternity bands | Lab-grown accent diamonds | No individual certificate |
| Earrings, bracelets, pendants | Lab-grown | No individual certificate |
What the grades mean
- D, E, F colour — the top three colour grades, the colourless range. The difference between D and F is very hard to see once set.
- VVS2 — inclusions very difficult to see even at 10× magnification.
- VS1 — minor inclusions visible only under magnification; eye-clean.
Our three combinations — F/VS1, E/VVS2, D/VVS2 — are all eye-clean and colourless. F/VS1 is the value choice; D/VVS2 is the top.

8. Education
Lab-grown vs mined diamonds
Lab-grown diamonds are real diamonds: the same carbon crystal, the same hardness (10 on the Mohs scale), the same brilliance. They are graded on the same 4Cs by the same laboratories. They typically cost 50–70% less than mined diamonds of the same quality, and involve no mining.
The 4Cs
- Cut — how well the diamond returns light; the biggest factor in sparkle.
- Colour — D (colourless) to Z. We sell D, E and F only.
- Clarity — from flawless down to included. We sell VVS2 and VS1.
- Carat — weight, not size. Shape changes how big a carat looks.
Moissanite is not diamond
Moissanite is silicon carbide — a different material, slightly softer (about 9.25 Mohs) and with more rainbow fire. Northfire sells only lab-grown diamonds, not moissanite.
Caring for your ring
- Clean with warm water, mild soap and a soft brush.
- Avoid bleach, chlorine and hairspray.
- Remove for the gym, swimming and cleaning.
- Store in its box; have the prongs checked by a jeweler once a year.
