Which size?

Find your ring size in a minute

Your screen becomes the sizer. Set it with a bank card, then measure the finger you will wear the ring on, with a ring that already fits that finger or with a strip of paper.

1. Set the screen with a card

Lay any bank, debit or ID card flat on the screen, standing tall, so its short edge runs across the box, and move the slider until the box is exactly as wide as the card. No bank card? A driver's license, metro card, gift card or hotel key is the same size. Without any card the circle and the ruler are not to scale: measure your paper strip with a real ruler and set that number in millimeters on the strip slider, then send it to the desk.

2. Measure

Take a ring that fits the same finger of the same hand the new ring will live on; every finger is its own size. Set it on the screen over the circle and move the slider until the circle just fills the inside of the ring.

Description

The Marquise Solitaire is a 2.50 carat lab grown diamond engagement ring built around a single statement: let the stone do everything. No accent band, no side stones — just a clean marquise-cut center stone in a classic prong setting on 14K gold, with a gallery rail underneath for structural support and a flush-fit profile that pairs seamlessly with any wedding band. The marquise cut's elongated silhouette flatters the finger and creates a larger visual presence than a round diamond of the same carat weight. Available in yellow, white, or rose gold. For buyers searching for a marquise diamond solitaire engagement ring that's as wearable as it is striking — this is it. Handcrafted in NYC.

Questions & answers

Is this your best price?

The price on this page is the price of the piece. Have a number in mind? Tap Make an offer and send it; the desk answers with what it can do. Paying by bank wire takes 3% off.

What is the center stone?

Center stone: 2.50 Ctw Marquise, lab-grown, F color, VS1 clarity. Lab-grown diamonds are real diamonds, grown in a lab instead of mined. Anything not shown here: Ask a jeweler.

Can I get it in another metal, with an engraving or another change?

The metals, colors and sizes this ring comes in are the choices above. Anything else (another karat, a different stone, an engraving, another size) is a custom order: Ask a jeweler with the item number and what you want; they say yes or no and quote it. Custom and personalized work is final sale.

What if the size is wrong? Can I return it?

Pick your size above; "Which size?" opens the store's ring sizer. A size we do not list, or a quarter size: Ask a jeweler before you buy. The weight can change slightly when the ring is sized; text a jeweler for the exact weight. Resizing is custom work and a resized ring cannot be returned. An unworn ring in its listed size can come back within 14 calendar days of delivery, on our label, less the 5% restocking fee and return shipping.

Does it come with a lab report?

This ring does not list a lab report. It ships with the store's appraisal, which lists the carat and gram weights and the diamond grade and color. A lab report for one stone before you buy: Ask a jeweler.

What if it is lost or stolen in the mail?

Every package is insured by us while it travels. Once FedEx marks it delivered, loss or theft is covered only if you add Optional Shipping Insurance at checkout.

What metal is it?

Real 14K Gold: 14 karat is 58.3% pure gold, alloyed with harder metals for strength.

Does it come with an appraisal or a certificate?

Every gold order ships with the store's appraisal: carat and gram weights, diamond grade and color, market value and the corporate seal. International orders get a digital appraisal.

How fast does it ship, and can I return it?

Every order ships insured from 47th Street. Usually ships in 15 to 20 business days. Returns: 14 calendar days from confirmed delivery, new and unworn, in the original packaging, on a label TraxNYC issues; an approved return carries a 5% restocking fee and $50 return shipping in the continental US ($100 international), and the original shipping is not refunded. Resizing is custom work, and a resized ring cannot be returned. Shipping policy · Refund policy
