Twenty-five promise rings, from $100 to $877, with most between $170 and $400. Twenty-four are solid gold. The collection is built around slim, understated designs — single small stones, split bands, trio settings, pearl and lab diamond solitaires.
The most useful thing this page can do is be clear about what a promise ring is and is not, because the distinction matters and getting it wrong sends a message you did not intend. Related: engagement rings, stackable rings, gemstone rings and gifts under $300.
Promise ring or engagement ring
These are not interchangeable, and the difference is understood widely enough that substituting one for the other will be read as a statement.
An engagement ring signals an intended marriage. It is traditionally worn on the left ring finger, and that position is itself part of the signal. Engagement rings here start around $480.
A promise ring signals commitment without a wedding date attached. It can be worn on any finger — the right hand and the ring finger of the right hand are both common — and it does not carry the implication of a timeline. Promise rings here start around $100.
Proposing with a promise ring is not a neutral choice. If the intent is a proposal, use an engagement ring; the difference in what is communicated is larger than the difference in price. Conversely, giving an engagement-style solitaire as a promise ring can imply more than intended, which is why the designs in this collection are deliberately quieter.
Other uses for a promise ring
Romantic commitment is the most common use but not the only one.
Promise rings are worn to mark friendship, particularly matching or paired rings between close friends or siblings. They are worn as personal commitments — a goal, a sobriety date, a decision. And they are given as pre-engagement rings where a couple is committed but a proposal is some way off, often for practical reasons like age, finances or distance.
In all of these the quieter designs work better, because a ring that reads as an engagement ring will be interpreted as one regardless of what it was meant to be. The plain bands, small solitaires and pearl designs here are the safest for that reason.
Which finger, and what it signals
There is no fixed rule, but there are conventions worth knowing because other people read them.
The left ring finger is the one to be careful with. Wearing a promise ring there will be read as an engagement ring by most people, which may be exactly what you want or exactly what you do not.
The right ring finger is the most common promise ring position and reads clearly as deliberate without the engagement implication.
The middle finger or index finger reads as jewelry rather than as a signal, which suits a personal commitment or a friendship ring.
Sizes differ between fingers by a full size or more, so measure the finger the ring is actually going on. Rings run US 4 to 8.5 including half sizes on most designs.
What is in the collection
Slim bands with a single stone
The largest group. Tiny lab diamond settings, small solitaires and minimalist designs. These are the pieces that work as promise rings without ambiguity — they read as a considered ring rather than as a proposal.
Pearl designs
Three pieces, including split-band pearl rings. Pearl is a distinctive choice here and worth a caution: it is the softest material in this catalogue, porous, and reactive to perfume, hairspray and skin oils. A pearl ring should not be worn constantly through manual work or cleaning. It is a beautiful choice for a ring worn regularly rather than permanently.
Trio and cluster settings
Four pieces group three or more small stones. The three-stone form carries its own quiet symbolism — past, present and future is the usual reading — without needing to be explained.
Split-band designs
Two pieces where the band divides and rejoins. Visually distinctive without being large, which is the balance a promise ring generally wants.
Rosary and pinky designs
Several pieces here work well on a pinky or as part of a stack, which suits a promise ring intended to be worn alongside other rings. See pinky signet rings.
Stones
Nine pieces use lab-grown diamonds, three pearl, two sapphire and one emerald. Lab-grown diamonds are chemically, structurally and optically identical to mined stones and cost substantially less, which is what allows a diamond-set ring at these prices. See diamond vs lab diamond.
If you want the stone to mark a birth month, note that garnet, amethyst and peridot are not currently stocked, so January, February and August are not covered. See birthstone jewelry.
Metal
Twenty-four of the twenty-five are solid gold — 14k at 58.3% purity, with the entry tier hallmarked 9K in the UK and Europe and 10K in the US. The gold runs throughout, so the ring can be repolished and repaired for decades.
The single vermeil piece is at least 2.5 microns of gold over solid 925 sterling silver — five times the thickness of ordinary plating, over a precious metal rather than brass. Vermeil is a reasonable choice for a promise ring worn intermittently, and a poor one for a ring intended to be worn permanently, because a ring takes more friction than any other jewelry. See why 14K solid gold and all vermeil.
Sizing and ordering
Everything is made to order, so size is fixed at production. Measure the base of the finger and over the knuckle and take the larger; measure at the end of the day when fingers are largest. If you are buying as a surprise, borrow a ring they wear on the same finger and measure its internal diameter. See the size guide and how to measure your ring size.
Production is 4–6 business days before dispatch. US orders ship from Connecticut with duties included; UK, EU, Canada and Australia orders from London. 365-day warranty. Engraved rings cannot be returned. See shipping and returns.
Matching rings, and how to make them work
Paired promise rings — one each for two people — are a common use for this collection, and there is a reliable way to do it that avoids the boxed-set look.
Share one element rather than matching exactly. The same metal, the same finish, or the same stone in two different settings reads as considered. Two identical rings read as bought together in a set, which is a different and generally weaker effect.
Width is the easiest variable to differentiate on: the same design in two widths suits two different hands and still reads as a pair. A slim version and a slightly wider one is the usual arrangement.
Measure both sizes independently and on the same evening. Fingers differ far more between people than most expect, and estimating one from the other is the most common source of a ring that does not fit.
Buying at this price point
Promise rings occupy a useful part of the range: solid gold, permanent, but at $100 to $400 rather than engagement-ring prices. A few things follow from that.
The pieces here are small by design rather than by constraint. A promise ring is meant to be understated, so the modest scale is the point rather than a compromise you are making for budget reasons. This is worth saying because a small solid gold ring sometimes reads as a lesser purchase when it is actually the correct one for the occasion.
What you are buying at this level is permanence in a modest form — solid 14k gold that can be repolished and repaired for decades. That is a better use of the budget than a larger piece in a material that cannot be restored. See all solid gold and gifts under $300.
Wearing a promise ring alongside other rings
Many of the designs here are slim enough to stack, which matters because a promise ring is often worn alongside existing rings rather than alone.
Two practical points. Several rings on one finger fit more tightly than one alone — if the promise ring will sit next to others, size a quarter to a half up for the outer position. And bezel settings are the safer choice in a stack, because a raised prong catches on a neighbouring ring, which is the most common cause of a loosened stone in stacked wear.
If the ring later needs to move — when an engagement ring arrives, for instance — a slim band transfers to another finger far more easily than a wide one. See stackable rings and Shop the stack.
Frequently asked questions
What is the difference between a promise ring and an engagement ring?
An engagement ring signals an intended marriage and is traditionally worn on the left ring finger. A promise ring signals commitment without a wedding date and can be worn on any finger. They are not interchangeable.
Can I propose with a promise ring?
It will not be read as a proposal by most people, and substituting one for the other sends a different message. If the intent is a proposal, use an engagement ring.
What is the price range?
$100 to $877, with most pieces between $170 and $400. Engagement rings here start around $480 by comparison.
Which finger should a promise ring go on?
The right ring finger is the most common and reads clearly without the engagement implication. The left ring finger will be read as an engagement ring by most people. Middle and index fingers read as jewelry rather than as a signal.
Do promise rings have to be romantic?
No. They are also worn between friends and siblings, and as personal commitments. The quieter designs here suit those uses better, because anything resembling a solitaire will be read as an engagement ring.
Is a pearl promise ring practical?
For regular rather than permanent wear. Pearl is the softest material in this catalogue, porous, and reactive to perfume and skin oils. It should come off for manual work and cleaning.
Are the diamonds real?
Lab-grown, which are real diamonds — identical composition, hardness and optical behaviour to mined stones, at substantially lower cost. That is what makes diamond-set rings possible at these prices.
What ring sizes are available?
US 4 to 8.5 including half sizes on most designs, with a small number at US 3 to 9. Rings are made to order, so size is fixed at production.
Should I buy solid gold or vermeil?
Solid gold for a ring worn permanently, because it can be repolished and repaired indefinitely and rings take more friction than any other jewelry. Vermeil is reasonable for one worn intermittently.
Can I engrave a promise ring?
Yes, and inside the band is the usual place. Engraved rings are made specifically for you and cannot be returned, so confirm the wording and the size first.
