How to propose marriage

The three questions to settle beforehand, how to find out their ring size without giving the game away, when and where — and what happens just afterwards.
By François Deprez, founder · Complete guide · 7 min · Updated August 2026

A successful proposal is not the most spectacular one. It is the one that reflects your relationship — and that has been prepared around the few points which, otherwise, can spoil the moment.

Every year, we guide hundreds of ring projects, and we always see the same questions come up: should you have the ring beforehand? How do you find out their size? Should you speak to the parents? Here is what we say.

01

The three questions to settle beforehand

01
A complete surprise, or not?

This is the real trade-off. An absolute surprise means having to guess everything — the ring, the moment, the desire. Many couples have already discussed marriage: the proposal is no less moving for it, simply anticipated. There is no right answer; there is yours.

02
Should you speak to the parents?

A custom, not an obligation. The right question is not “is that what one does?” but “will it matter to the person concerned?” If so, do it before, never afterwards. In some families, omitting it leaves a mark.

03
Just the two of you, or surrounded by others?

Privacy remains by far the most common choice, and it is safer: a proposal in front of witnesses puts real pressure on the answer. Many couples save their loved ones for the announcement, just afterwards — it offers the best of both worlds.

A question with no answer

“How long can we remain engaged?” — no rule. Most often, from a few months to two or three years, sometimes longer. In France, an engagement has no legal value: its duration depends solely on you and the time needed to organise the wedding.

02

The ring: before or after the proposal?

It is the question we are asked most often, and tradition alone no longer provides the answer. Both approaches are practised, and neither is more romantic than the other.

The approach What it offers What it costs
Arriving with the ring Tradition The effect remains intact. The gesture is complete; the object is there. You need to guess a very personal taste, and the size.
A temporary ring The surprise is preserved, and the real ring is then chosen together. Requires owning a symbolic object on the day itself.
Without a ring Everything is decided together, from the first sketch to the stone. The moment rests entirely on the words.

For bespoke creations, the second and third options are the ones we see most often. The reason is simple: an engagement ring is worn for a lifetime, and the pleasure of designing it together is often worth more than the element of surprise. Our page bespoke creation describes how a project unfolds, from the stone to the finished piece of jewellery.

If you choose to arrive with the ring, here are two guidelines to avoid getting it wrong. The first: the stone before the setting. It is what one looks at, and it is what carries the budget. The second: a coloured stone is more forgiving than a diamond. It signals a personal choice rather than a standard, and offers considerably greater volume for the same budget.

For inspiration: our sapphire engagement rings — including teal sapphires, the most sought-after shade of the moment —, our diamond rings for tradition, and our tourmaline rings for going off the beaten track. Our creations show what others have chosen.

Knowing her size without giving the game away

This is the number one obstacle in any surprise proposal. Four methods, from the most reliable to the most hazardous:

  • Borrow a ring she already wears on her ring finger — one evening is enough — and have it measured by a jeweller. This is the only truly reliable method. Note: a ring worn on another finger will not give the correct size.
  • Ask a close friend or her mother. They often know, and they are better at keeping a secret than one might think.
  • Measure the inside diameter of an existing ring with a ruler: the finger circumference in millimetres is approximately the diameter × 3.14. Approximate, but better than nothing.
  • Compare with the finger of someone close to her with a similar build. The riskiest method, to be used only as a last resort.
The safety net

A ring can usually be resized afterwards — it is a standard workshop operation. If you have to gamble, err on the slightly large side : a ring that is too small will not go on on the day, while a slightly loose ring can still be worn. And bear in mind that a wide band is worn half a size larger than a thin one, and that fingers swell at the end of the day and in warm weather.

04

When to propose

There is no universally right moment — only moments that make sense for you. The most common:

  • The anniversary of your first meeting, or another date that belongs only to the two of you. It is the most frequently mentioned choice, and the hardest to make unexpected.
  • During a holiday or weekend away, far from everyday life — the setting helps, and you have time ahead of you.
  • After a happy event : a professional success, a move, good news. The momentum is already there.
  • A festive period — Christmas, Valentine’s Day, a birthday. Warm, but highly anticipated: the surprise suffers.
  • A perfectly ordinary day. That is when the effect is strongest, because nothing had announced it.

One timing point not to overlook: a bespoke creation takes several weeks, between selecting the stone, the design and the workshop. If your date is set, get ahead of us.

05

Where, and how to make it unique

Originality almost never lies in the place itself. It lies in what the place means to the two of you: the spot of your first date is better than a palace where you have no memories.

That said, certain settings lend themselves to the moment: the water’s edge, a bridge, a boat, a beach at a quiet hour, a mountain chalet, a park at dawn, a night train. And certain stagings work very well: slip the proposal into a book currently being read, into a bouquet, into an object placed along a walking route.

Two classic mistakes

The audience. A crowded restaurant or a stadium imposes an immediate answer in front of witnesses — many people hate that, and sometimes you only discover it at the very moment. And the logistics. A proposal at the top of a four-hour hike, in the rain, after an argument about the route: the beautiful idea rarely survives the reality of the terrain.

06

The moment itself

Down on one knee remains the expected gesture, and it works — provided it suits your relationship. Some people dream of it; others would feel embarrassed. You know which kind of person you have in front of you.

The words matter more than the staging. No speech is needed: three sentences are enough, spoken while looking at each other. What moves her is the specific — a precise memory, something she does that you love, what you want to build together. General phrases, on the other hand, are forgotten within the hour.

The finger. In France, the ring is worn on the left ring finger. This is not universal: in Germany, Poland, Russia, Spain or Greece, it is the right ring finger. If you are proposing abroad or in a binational couple, our guide which finger to wear an engagement ring on covers the question in full.

The photograph. If it matters to you, ask someone to take it discreetly, from a distance. A phone set up on a tripod frames poorly and is noticeable. But do not let the photograph dictate the moment: it is the most common pitfall of planned proposals.

07

And just afterwards?

Four things no one thinks about in the moment, and which all happen within the week:

  • The announcement. Plan who you will call first — families rarely appreciate finding out through social media.
  • Resizing. If the ring is loose or tight, this is a common workshop procedure. Have it done quickly: a ring that is too large can be lost.
  • Insurance. A valuable ring must be declared to your insurer, along with the invoice and the stone certificate. It takes ten minutes and prevents a disaster.
  • The wedding band. It will sit beside the engagement ring, and the two must fit together. It is easier to plan for this early on — see our guide which hand to wear your wedding band on and where to wear your engagement ring after marriage.

And to end with what matters most: ring, place, words — every detail deserves thought — but it is sincerity that makes the proposal. How you phrase it will matter far less than the fact that it is truly you speaking.

08

Everything you are wondering before taking the plunge

Should you have the ring before proposing?

Both approaches are common. Arriving with the ring preserves the surprise but means guessing a very personal taste. Proposing with a temporary ring — or without one — then choosing the real one together is common today, and is what we see most often in bespoke creation.

How can you find out her ring size without giving the game away?

Borrow a ring she wears on her ring finger and have it measured — that is the only reliable method. Otherwise, ask a friend or her mother. As a last resort, err on the slightly larger side : in most cases, a ring can be resized afterwards.

How long can you stay engaged?

There is no rule. Most often, from a few months to two or three years. In France, an engagement has no legal value: the duration depends entirely on you.

Should you ask the parents for their blessing?

A custom, not an obligation. The right question is: will it matter to the person you are going to propose to? If so, do it before the proposal, never afterwards.

What budget should you allow for an engagement ring?

The three months’ salary rule is an advertising argument from the 1930s, not a standard. Our creations start at around 2 500 €, with the core collection ranging between €4,500 and €12,000. A stone-by-stone breakdown is available in our sapphire price guide.

Which finger should the ring be worn on?

In France, on the left ring finger. In Germany, Poland, Russia, Spain or Greece, it is the right ring finger — the full answer can be found in our dedicated guide.
