TL;DR:
- You can get a solid matching promise ring set for two people for $15-$60 total — stainless steel and titanium sets dominate this price bracket.
- Titanium causes allergic reactions in fewer than 0.6% of wearers, while 316L stainless steel still carries 10-14% nickel by weight (locked in the alloy, not loose on skin).
- Tungsten carbide rings (Mohs 8.5-9) resist scratches better than steel or titanium, but they crack instead of bending if dropped — a trade-off worth knowing before you buy.
A promise ring is a physical marker of commitment — worn before an engagement, sometimes instead of one. I’ve spent two decades sourcing rings for factories that ship to retailers exactly like the sellers on this list, and the under-$100 promise ring market runs almost entirely on three metals: stainless steel, titanium, and tungsten carbide, with the occasional sterling silver piece. If you’re weighing a promise ring versus an engagement ring for your relationship, price point is usually where couples start narrowing down. Below are 15 matching sets, all under $100 per pair, with the material facts that actually matter before you buy.
What Makes a Promise Ring Different From an Engagement Ring?
A promise ring signals commitment without a marriage plan attached, while an engagement ring specifically means a wedding is being planned. Promise rings can be given at any relationship stage and worn on any finger — there’s no rulebook.
According to The Knot, promise rings often function as placeholders in long-distance relationships or as a milestone marker before either partner is ready for a formal proposal. That’s exactly why the material matters more here than the carat count — these are everyday rings, not once-a-year occasion pieces, so they need to survive dish soap, gym bags, and forgetting to take them off in the shower.
1. Lam Hub Fong Personalized Promise Rings for Her
This set comes with 2 simulated birthstones and an interior engraving option for a date, phrase, or names. The engraving sits on the inside of the band, and the design works for anniversaries and Valentine’s gifts as easily as a promise exchange. Check current price on Amazon.
2. MABELLA 3-Piece Hers His Stainless Steel Promise Rings
Made from stainless steel with cut cubic zirconia on the women’s ring, this set runs sizes 5-10 for her and 9-13 for him — a wider size range than most sets on this list, which matters if either of you falls outside standard ring sizing. Check current price on Amazon.
3. ANAZOZ His & Hers Real Love Heart Promise Rings
These 6mm stainless steel rings split a heart design between the two bands — half the heart on each ring, so they only “complete” when the pair is together. Each ring also doubles as a necklace pendant. Check current price on Amazon.
Is Stainless Steel Safe if You Have a Nickel Allergy?
Most nickel-sensitive people tolerate 316L stainless steel because the nickel is locked into the alloy rather than sitting loose on the surface. If you’ve had a severe, documented nickel reaction before, titanium is the safer bet.
Nickel triggers an allergic reaction in roughly 15% of the population, according to the Mayo Clinic. Jewelry-grade 316L stainless steel still contains 10-14% nickel by weight, but the way it’s bound in the metal’s structure means most people never notice. Titanium, on the other hand, causes reactions in fewer than 0.6% of wearers — that’s why piercers recommend it for fresh piercings and sensitive skin. If a listing just says “alloy” without naming the grade, I’d assume it contains nickel and treat it accordingly.
4. ANAZOZ I Love You His & Hers Matching Rings
Made of 925 sterling silver, hers has stones set along an infinity design while his carries the infinity shape alone. Sterling silver runs softer than steel or titanium (2.5-3 on the Mohs scale versus titanium’s 6), so expect more surface scratching over years of daily wear — that’s the trade-off for the warmer silver tone. Check current price on Amazon.
5. Global Jewelry His King, Her Queen Titanium Promise Rings
His ring runs 7mm thick and hers 5mm, both in titanium-stainless steel with corrosion resistance built in. Titanium sets like this one are the ones I point sensitive-skin customers toward first — no nickel to react to, full stop. Check current price on Amazon.
6. Fate Love Pure Black Matching Couple Rings
His ring measures 8mm, hers 6mm, both finished in black stainless steel — also available in blue, gold, and silver if black isn’t your style. The black coating on steel rings is typically an ion-plating process, which holds up well as long as you avoid abrasive cleaners. Check current price on Amazon.
7. Fashion Ahead Matching Promise Rings
Hers comes in a rose gold finish, his in black, both in stainless steel with a “His Queen / Her King” engraving on the exterior and a grooved interior to reduce moisture trapping against skin. Check current price on Amazon.
How Much Should You Actually Spend on a Promise Ring?
Most matching promise ring sets under $100 land between $15 and $60 for the pair, and that price gets you real durability — stainless steel and titanium both outperform cheap plated brass. Spending more only makes sense once you want solid gold or genuine gemstones.
I’ve seen customers assume a higher price always means better quality, but in this bracket that’s rarely true — you’re paying for engraving options, packaging, and brand markup more than material upgrades. For a deeper breakdown of what different price tiers actually buy you, see our guide on how much to spend on a promise ring.
8. Global Jewelry We Love Each Other Couple Promise Ring
Crafted from titanium-stainless steel with matching heartbeat and heart-shaped engravings, his ring is 6mm and hers 4mm — a proportional pairing that reads well side by side on camera or in person. Check current price on Amazon.
9. LerchPhi Personalized Engraved Promise Rings
Made of tungsten carbide with a satin black finish and rose gold interior. Tungsten carbide rates 8.5-9 on the Mohs hardness scale — close to diamond’s 10 — so it resists everyday scratches better than steel or titanium. The trade-off: tungsten doesn’t bend under impact, it cracks, so it’s not the ring to wear doing heavy manual labor or sports. Each piece is priced individually. Check current price on Amazon.
10. NYCJewelrydesign His & Hers Promise Rings Set
Hers is genuine 925 sterling silver with a 2-piece design and multiple cubic zirconia stones; his is solid titanium at 8mm with a rope-twist pattern. Mixing metals across a couple’s set like this is common in this price range — it lets each ring suit different skin sensitivities. Check current price on Amazon.
11. LaRaso & Co. His and Her Wedding/Promise Rings
Her ring pairs a 7mm x 7mm center CZ stone on a sterling silver band, while his is brushed stainless steel — a two-toned combination that works equally well as a promise or wedding set. Check current price on Amazon.
12. Wedding Ring Set His Hers Couples’ Matching Promise Rings
His ring is stainless steel with a silvery exterior and blue interior; hers is a two-piece white gold ring set with blue stones and a centered heart-shaped CZ. Both are hypoallergenic and priced for everyday wear rather than special occasions only. Check current price on Amazon.
13. Wedding Ring Set His & Hers Promise Rings
Hers pairs gold-plated, square-cut cubic zirconia on a 2-piece white-gold-plated base; his is an 8mm tungsten carbide band — strong, scratch-resistant, and corrosion-proof. Check current price on Amazon.
14. Marimor Jewelry His and Hers Promise Rings
Her ring features a 2.10-carat total weight princess-cut CZ setting on a stainless steel base; his is also stainless steel, available from 4mm to 8mm depending on preferred thickness. Check current price on Amazon.
15. Knot Theory Silicone Wedding/Promise Ring
A silicone-and-rubber alternative rather than metal, this ring comes in reds, pinks, greens, and black, and it’s built to be worn during workouts, manual labor, or anywhere a metal band would be a liability. If either of you works with your hands or lifts weights regularly, this is worth considering as a daily-wear pairing to a metal set kept for going out. Check current price on Amazon.
Which Finger Do You Wear a Promise Ring On?
There’s no fixed rule — promise rings go on whichever finger feels right, though the left ring finger and the right-hand ring or middle finger are the most common choices among couples.
Unlike engagement rings, promise rings don’t carry a cultural placement standard. Some couples deliberately choose the left ring finger to visually echo an engagement ring; others pick the right hand specifically to avoid that comparison. If you’re still deciding whether a promise ring fits your relationship stage at all, our piece on whether any ring can be a promise ring covers the etiquette in more depth.
The Bottom Line
For most couples shopping under $100, a stainless steel or titanium set gives you the best combination of durability and price — expect to pay $15-$60 for the pair. Go titanium if either of you has sensitive skin, tungsten carbide if scratch resistance matters more than flexibility, and sterling silver only if you’re prepared to polish out surface scratches over time. Whatever you pick, get the engraving — it’s usually free and it’s the detail that makes a $20 ring feel personal. Browse more of our jewelry buying guides before you check out.
Frequently Asked Questions
Do promise rings have to match?
No, but matching or coordinated sets are popular because they visually tie the couple together without requiring identical rings. Many sets on this list use complementary designs — like a split heart or shared engraving — rather than identical bands.
Can you wear a promise ring every day?
Yes, and most people do. That’s exactly why stainless steel and titanium dominate the under-$100 category — both hold up to daily wear, water exposure, and accidental knocks far better than plated or silver-plated alternatives.
What is the average price of a promise ring?
Individual promise rings in stainless steel or titanium typically run $10-$50 per ring, while matching sets for two people land between $15 and $60 total. Sterling silver and tungsten carbide options push toward the higher end of that range.
Is a promise ring the same as an engagement ring?
No. A promise ring signals commitment without a marriage plan attached, while an engagement ring specifically accompanies a marriage proposal. See our full comparison on promise rings versus engagement rings for the details.
What metal is best for a promise ring if you have sensitive skin?
Titanium is the safest choice — it causes reactions in fewer than 0.6% of wearers because it contains no nickel at all. 316L stainless steel works for most people too, since its nickel content stays bound in the alloy rather than contacting skin directly.
Should you give a promise ring before an engagement ring?
It’s common but not required. Promise rings often mark a relationship milestone — moving in together, surviving long distance, or a shared anniversary — well before either partner is ready for a formal proposal.
