Men's Moissanite Rings: Sizing, Cuts and Which Metal Lasts

Every ring in this guide is in the men's rings collection.

Men's rings get bought wrong more than any other jewelry, usually on size. A ring that is half a size too big spins the stone to the palm; half a size too small does not go over the knuckle. Here is how to get it right, then how to pick the stone and metal.

Sizing at home

Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length in millimetres. Divide by 3.14 for the inner diameter. Then: 18.1 mm is US 8, 19.0 mm is US 9, 19.8 mm is US 10, 20.6 mm is US 11, 21.4 mm is US 12. Measure at the end of the day when fingers are largest, and if you are between sizes on a wide band, size up; wide bands fit tighter than thin ones.

Cuts that work on a men's band

Round is the safe choice and the brightest. Emerald cut suits a wider, flatter band because its long straight facets echo the band's lines; the S925 emerald cut moissanite ring is the example. Marquise is the boldest, a long pointed stone that makes the finger look longer; the marquise moissanite ring in sterling silver shows it in a plain setting. Black moissanite, as in the black moissanite stack ring, reads as a signet rather than a gemstone ring.

Why we set men's rings in S925

A ring takes more abuse than any other piece: it hits doors, desks and weights. Gold plating over brass wears through at the bottom of the band within months of daily wear and exposes yellow-brown metal. S925 sterling silver is solid all the way through, so scratches polish out and the ring can be resized. That is why the S925 six-prong moissanite ring at $29.99 will outlast a plated ring at the same price.

Stone size

On a men's hand, 1 carat (6.5 mm round) is a normal stone; 2 carat (8 mm) is noticeable; 3 carat (9 mm) is a statement. The round moissanite sterling ring is the plain 1-carat version. Above 3 carat, the setting height makes the ring catch on things.

Matching sets

If you are buying with a partner, the moissanite couple rings set is sized as a pair. Otherwise the men's rings collection can be filtered by cut and metal.
