Necklace for Boyfriend: What to Buy, Sizes and Prices (2026)

The best necklace for your boyfriend is one that fits how he already dresses: a thin tennis chain or a plain Cuban link if he keeps it low-key, a wider iced chain if he already wears jewelry, and a name or cross pendant if you want it to mean something. Get the length right (20 inches suits most men) and spend what you'd spend on any good gift, because a necklace is worn every day, not once.

We've sold jewelry to more than a million customers since 2019. This guide covers which styles men actually wear, real prices from $249.99 as of November 2, 2026, how to guess his length without asking, and the return rules you need to know before you buy a gift.

What kind of necklace should I get my boyfriend?

Start with what he wears now, not what you'd like him to wear. The gift that gets worn is the one that fits his existing style. Look at three things: his watch (if any), how he dresses on a normal weekend, and whether he's ever worn a chain before.

He doesn't wear jewelry yet

Go thin and quiet. A 1.5mm micro tennis chain or a 3mm tennis chain reads as a clean line of sparkle under a T-shirt collar. It doesn't look like he's trying hard, which is what a first-time chain wearer worries about. Silver finish is the safest color: it goes with every watch and every outfit.

He already wears a chain or a watch

He'll want something a step up from what he owns. If he wears a thin chain, a 5mm or 6mm tennis chain is the natural upgrade. If he likes gold, a 10mm Cuban link in a gold finish works with almost everything. Match the metal color to his watch where you can.

He likes a statement

Wide iced chains are made to be seen. Our 10mm clustered tennis chain was our top-selling piece by sales over the last 30 days. If he wears hoodies and oversized tees, this is the lane.

You want it to mean something

A pendant carries the message. A name or initial pendant is the most personal option. A cross pendant is a common choice if faith matters to him. Keep the chain under a pendant simple so the pendant does the talking.

Necklace for boyfriend ideas by budget

These are in-stock moissanite necklaces from our store, with live prices. Every stone is D color VVS1 moissanite with a GRA report, and every piece comes with a lifetime warranty card. Prices run from the shortest to the longest length.

Under $300

Two very different options sit here. The micro tennis chain is a fine 1.5mm line of stones, about 3.9 carats in total at 18 inches. The 10mm Cuban Moissanite Clasp Chain is a plain gold-finish Cuban link with moissanite set only in the clasp, so it looks clean from the front and catches light where it closes. Pick the micro chain for a man who wants sparkle, the Cuban for a man who wants gold.

$300 to $500

This is where we'd point you if you're unsure. The 3mm Moissanite Tennis Chain is thin enough for a man who has never worn a chain and still has real stone weight: about 14 carats at 18 inches, rising to 18.7 carats at 24. The 5mm tennis chain is the same idea with bigger stones, for a man who already wears something thin.

$500 to $800

The 6mm tennis chain and the 10mm clustered tennis chain are statement pieces. The 6mm comes in silver or 18K gold plating at the same price. The 10mm clustered chain packs stones into wider links, so it looks heavier and louder. Buy these for a man who already likes being noticed.

Under $150: our CZ line

If your budget is lower, our cubic zirconia chains use CZ simulant stones and plated metal, not moissanite. Our 4.5mm CZ tennis chain is $99.99 to $114.99 as of November 2, 2026. CZ looks good on day one, but it's softer (about 8 to 8.5 on the Mohs scale, against 9.25 for moissanite), so it scratches and dulls sooner. One plus for a gift: CZ pieces can be returned if unworn, which moissanite pieces can't (more on that below).

Personalized necklace for boyfriend: name, initials and cross pendants

"With name" and "with initials" are two of the most common ways people search for a boyfriend necklace, and for good reason: nobody else has the same one.

Our custom moissanite pendants are made to order. The Custom Moissanite Baguette Font Pendant, a name plate in baguette and round moissanite, is $695.99 to $1,116.99 as of November 2, 2026, depending on size. Three things to know before you order one:

• Timing. Custom pendants take 4 to 6 weeks to handcraft, then ship tracked. Count back at least 7 weeks from the day you want to give it.
• Chain. Our custom pendant listing says each pendant comes with a 4mm rope chain, and the pendant loop is 5mm wide, so it won't fit tennis chains wider than 5mm.
• No returns. Custom pieces are built for one person and can't be returned. They're still covered by the lifetime warranty.

If you need it sooner, a ready-made pendant ships like any in-stock piece. Our Moissanite Cross Pendant in silver finish is $149.99 to $169.99 as of November 2, 2026.

What chain length should I get my boyfriend?

This is where most gift necklaces go wrong. Chain length is measured end to end, and the same chain sits differently on different necks. If you can't ask him, use this:

Two ways to find his size without asking:

• Measure a chain he already wears. Lay it flat in a straight line, clasp to clasp, and measure it. Buy the same length.
• Check his shirt collar size. Look at the tag on a dress shirt. Add about 4 inches and round to the nearest standard length to land on the collarbone. A 16-inch collar means a 20-inch chain.

Wide chains sit higher than thin ones, so go one size longer for anything 10mm or wider. Our full chain lengths for men guide has the details and a neck-size method.

Silver or gold necklace for boyfriend?

Silver finish is the safer gift if you're unsure. It matches steel watches and goes with black, white and grey. Gold suits a man who already wears gold or has a gold watch, and it stands out more against dark clothes.

A note on what "gold" and "silver" mean on our pieces, because it matters: our moissanite chains are plated. The silver-finish pieces use 18K white gold plating and the gold pieces use 18K gold plating, both applied with PVD reinforcement. They're not solid gold. Our lifetime warranty covers fading, discoloration and tarnishing of the finish, so if the plating wears, we repair or replace the piece.

Is a necklace a good gift for a boyfriend?

Yes, if it's one he'll wear. A chain is one of the few gifts a man uses every day, and unlike clothes, it doesn't go out of season. The risk is buying for the man you picture instead of the man you have. If he's never worn jewelry, a thin chain is a better bet than a loud one. If he already wears jewelry, a chain wider than what he owns is a better bet than another thin one.

5 mistakes people make buying a necklace for a boyfriend

1. Guessing the length. 16 inches is common in women's jewelry and too tight on most men. Default to 20.
2. Going too loud for a first chain. A man who has never worn jewelry rarely starts with a 10mm iced chain.
3. Mixing metals with his watch. A gold chain next to a steel watch can look accidental. Match where you can.
4. Ordering custom too late. Made-to-order pendants take 4 to 6 weeks before they ship.
5. Not checking what you're buying. "Diamond look" can mean CZ, moissanite or lab diamond. Our moissanite pieces come with a GRA report and pass a standard diamond tester. Our best chains for men guide compares the styles side by side.

How fast will it arrive?

In-stock pieces ship from our US warehouse and arrive in 1 to 2 business days in the US. Orders placed before 2pm ET on a business day ship the same day, and tracked delivery is free on orders over $100. If a piece isn't in US stock, it ships from our UK warehouse in 5 to 10 business days, and the product page tells you before you order. Custom pendants follow the 4 to 6 week timeline above.

Necklace for boyfriend: common questions

What is a good necklace for my boyfriend?
A 3mm tennis chain in a silver finish is the safest pick for most men: subtle enough for a first chain and easy to wear every day. If he already wears jewelry, go wider, like a 5mm or 6mm tennis chain.

What length necklace should I get my boyfriend?
Buy 20 inches for a plain chain and 22 inches for a chain with a pendant if you don't know his size. Go one size longer for chains 10mm or wider.

Is a necklace a good gift for a boyfriend?
Yes, if it matches his style. A chain is worn every day, so it gets more use than most gifts. Keep it thin if he doesn't wear jewelry yet.

What should I engrave or put on a necklace for my boyfriend?
Most people choose his name, his initials, or a short word that means something to both of you. Shorter text reads better on a pendant.

How much should I spend on a necklace for my boyfriend?
The moissanite necklaces in this guide cost $249.99 to $799.99 as of November 2, 2026. Our 4.5mm CZ tennis chain is $99.99 to $114.99 if you need to spend less.

Can I return a necklace if it's the wrong size?
Moissanite pieces are final sale, so check his length first. CZ line pieces can be returned within 14 days of delivery if unworn with the film on, or exchanged within 90 days.
