Men's Diamond Ring Guide

None of these are rules. They are the reasons people make the choice. The practical point: rings on the index and middle fingers take more knocks, so they need sturdier settings. The pinky is the most protected finger for a big diamond top. See our diamond pinky rings for that look.

Width is measured across the top of the ring in millimeters. It decides how bold the ring looks and how it feels.

Wider rings feel tighter than thin ones in the same size, because they cover more of the finger. Many jewelers suggest going up a quarter or half size for bands of about 8 mm and wider. Gold weight tells you how solid a ring is. Our men's rings range from 3.63 grams for a band to 16.21 grams for a full signet.

Comfort fit matters on wide rings. A comfort-fit band is rounded on the inside, so it slides over the knuckle more easily and feels lighter than a flat-inside band of the same width. Ask how the inside of the ring is shaped before you buy a wide band.

An eternity band has stones all the way around, so sizing has to be right the first time. Signets give the most surface for diamonds and the most presence. A Cuban ring is the natural match if your chain is a Cuban.

Men's hands hit things: steering wheels, weights, doors, desks. The setting decides whether the diamonds stay put.

• Flush (gypsy) setting: the stone sits in a hole drilled into the metal, level with the surface. Almost impossible to snag. Best for working hands.
• Channel setting: stones held between two metal walls in a row. Strong and clean.
• Bezel: a metal rim around each stone. Very protective.
• Pavé: many small stones held by tiny beads. Maximum sparkle; check it every few months.
• Prong: claws holding a stone up. The most light, but the most exposed. Fine on a pinky signet, risky on a hand that lifts.

Baguettes, the long rectangular stones in many signet rings, usually sit in channels or tight rows, which is part of why they suit men's rings. Our guide to melee and pavé explains small-stone setting in depth.

Every men's diamond ring in our catalog is 10K gold, made to order in yellow, white or rose gold. Here is how they compare:

Notice what drives price. The Square Baguette Signet has fewer carats than the Zeus band but costs more, because baguette work and a heavy signet top take more gold and more setting time. The Classic Eternity Band carries 4.38 carats on just 3.63 grams of gold: almost all diamond.

Women's rings are often one big stone. Men's diamond rings usually go the other way: many stones spread across a wide surface.

For most men, a pavé or baguette top gives more presence per dollar and wears better. A single large stone is a choice for people who want one serious diamond and are careful with their hands. If you want something nobody else wears, our custom men's rings start from your idea, with a design and exact price before anything is made.

Men's ring sizes usually run larger than women's. The US scale steps up in half sizes; each full size adds about 0.8 mm to the inside diameter.

Measure at the end of the day, when fingers are largest, and measure the exact finger you will wear it on. Your pinky is several sizes smaller than your ring finger. Knuckles matter too: the ring has to pass over the knuckle and still not spin at the base. Since all sales are final with no refunds at Franky Diamonds, get the size right before you order, ideally by trying sizes on in the showroom.

All of our men's diamond rings are 10K gold, and that is a practical choice. 10K is 41.7% gold and harder than 14K or 18K, which matters on a ring that gets knocked around and carries a wide diamond top. It also keeps the gold part of the price down, so more of the budget goes into stones.

• Yellow gold is the classic men's look and pairs with gold chains and watches.
• White gold makes a diamond top read as one bright sheet of ice.
• Rose gold is less common on men and stands out for that reason.

Pick the color that matches the watch or chain you wear most. A ring that matches what you already own gets worn every day.

• Match metals on the same hand. A yellow gold ring next to a yellow gold watch looks planned.
• Balance the hands. Watch on one wrist, statement ring on the other hand, or a bracelet with the watch and a ring on the opposite pinky.
• One loud piece per hand. An iced watch plus a big signet on the same side competes.
• Match the stone style. Baguette ring with a baguette bracelet, pavé ring with a pavé bezel.

Our 10K baguette bracelets, such as the Round Baguette Bracelet at $5,120, pair naturally with the baguette signets above. For the full look, see men's jewelry, men's chains and men's diamond earrings, or all men's diamond rings.

More men now choose a diamond band instead of plain gold for their wedding ring. A few points if that is your plan:

• Pick a band, not a signet. Wedding rings are worn every day for years, so an even-width band is more comfortable than a raised top.
• Choose a protective setting. Channel or flush-set stones survive daily wear far better than prongs.
• Consider a partial setting. Stones across the top only, instead of all the way around, keep the inside of the hand smooth and make future sizing simpler.
• Match the metal to hers, or choose a deliberate contrast.
• Get the size right at the end of the day, when fingers are at their largest.

The Zeus Diamond Band and the Classic Eternity Band above are the two band styles in our men's line. Both come in yellow, white or rose 10K gold.

1. Take it off for the gym, contact sports and manual work.
2. Soak it in warm water with a drop of mild dish soap and scrub under the top with a soft toothbrush. Grime under a signet dulls every stone.
3. Check the stones under a light every few months. A dark spot where a stone should be means it is time for a bench check.
4. Store it alone, not loose in a drawer with other rings and a watch.
