“Start with a beautiful ring on a great band, and think about the wedding bands that go with it.” Trax, at the jewelry store on 47th Street

The Clara five-stone sold most, 13 in the year, just ahead of the Lumiere solitaire on a pave band.

Buyer's guide
How to choose an emerald cut engagement ring
Learn the cut, then pick the setting, the carat and grades, the stone and her size
Every ring here holds an emerald cut diamond, a long rectangle with flat, stepped facets, not the green emerald stone. That open face lets you see into a diamond, so buy clarity before carat. Start near two to three carats, the weight most buyers chose. Every ring bought had a lab-grown center, nearly all in 14K gold. Pick the setting she will wear every day, and read her size from a ring she owns.

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.
Size 5, 15.7 mm inside
Wrap a strip of paper snug around the base of the finger, where the ring sits, and mark where it meets. If your knuckle is bigger, wrap it there too and take a size between the two, nearer the knuckle. Lay the strip along the ruler's right edge from the 0. Move the slider until the gold line sits on your mark.
49.5 mm around is size 5
Size 5: 15.7 mm across, 49.3 mm around. 15 of the 18 rings here list size 5.
Between two sizes? Take the one that passes the knuckle and sits snug below it. A wide band, 8 mm and up, fits tighter, so go up a half size. Measure at the end of the day, at room temperature.

Questions we get in the store
Is an emerald cut engagement ring an emerald stone?
No, every ring here holds a diamond. Emerald cut names the shape, a long rectangle with trimmed corners and flat stepped facets, borrowed from green emeralds. For the green stone itself, see our women's gemstone rings.
What carat emerald cut diamond should I buy?
Two to three carats, the center most buyers chose. An emerald cut of two carats is about 9 by 6 mm face up. The biggest centers here reach five carats, for a ring that reads across a room.
What clarity and color does an emerald cut need?
Buy VS clarity or better, because the open steps show the inside of the stone more than a round does. A tint shows more too. Every center that states a grade is D to F color and VS or better, several of them VVS.
More questions we get
Lab-grown or natural emerald cut diamond?
Lab-grown, going by what people bought, since every ring sold in the year had a grown center. Both are real diamond, graded on the same letters. One ring holds a natural center, set in 18K gold.
Which setting suits an emerald cut diamond?
Pick a solitaire to show the step cut alone, or side stones to make the ring read wider. The Clara, with its side stones, and the Lumiere, one stone on a pave band, were bought most. Check that all four corners are covered.
Can I see an emerald cut ring in person before I buy?
Yes. Come to our showroom at 64 W 47th Street, open seven days. Tell the live chat which ring you want to see, or call or text 212-872-9692 from 10 AM ET, and we will say whether it is in our store or made to order.
How do I get her ring size if the proposal is a surprise?
Borrow a ring from her ring finger and check it on the sizer on this page, or ask a friend who knows. If it is off after she says yes, ask the desk whether it can be resized; a resized ring is final.
Can I return an emerald cut engagement ring?
Yes, an unworn, unaltered ring from the case, within fourteen days of delivery. Start the return on the live chat; it goes back on our insured label, and the refund keeps back that label and five percent restocking. Made-to-order sizes, resized rings and custom work are final.
