At Laveran Paris, a PACS ring costs from €90 in 925 silver, €320 in 18k gold for a men's band, €536 for a half-eternity band set with lab-grown diamonds and €856 for a matching pair for her and him.

Do you need a ring for a PACS?

No: a PACS requires no ring, no exchange of bands and no ceremony. It's a contract signed by both partners and registered at the town hall or with a notary. The ring is a personal choice, not a step in the procedure.

So, ring or no ring? More and more couples choose one, because a PACS is still a strong commitment: living together, building a shared future, protecting each other. A ring gives that moment a visible form that you then wear every day. Three situations come up often:

• A ring given by one partner to the other, as a PACS gift.
• Two matching rings, chosen together and worn by both partners.
• A ring for now, when the PACS comes before a future wedding: it will later be worn with the engagement ring or wedding band.

PACS ring or PACS band: what's the difference?

"PACS ring" and "PACS band" describe the same piece: a ring chosen freely to mark the PACS. The difference from marriage lies in custom, not in the jewelry itself.

A PACS ring is also close to a promise ring: a commitment with no wedding date. See our guide: promise rings, meaning and advice.

Should you give a diamond for a PACS?

It isn't necessary, but it's a beautiful choice: a diamond symbolizes a strong, lasting bond, which is exactly what a PACS celebrates. Long reserved for engagements, diamonds are now worn on freer commitment rings too.

A lab-grown diamond (also called a synthetic diamond) makes this choice accessible. It's a real diamond: pure carbon, with the same hardness and the same brilliance as a natural diamond. Only its origin differs, and it costs up to 80% less than a natural diamond. At Laveran, every diamond is IGI or GIA certified with no fluorescence.

Three ways to wear a diamond for a PACS:

• A diamond half-eternity band: a line of small diamonds, discreet and luminous, that can later be worn with an engagement ring.
• A small solitaire: a 0.30-carat center stone, for a real symbol without ostentation.
• A plain men's band next to a diamond ring for her: the most common pairing.

Which finger is a PACS ring worn on?

Most often on the ring finger: on the left hand like a wedding band, or on the right hand to keep the left free for a future wedding. There is no official rule for a PACS.

• Left ring finger: the most common choice in France, by analogy with the wedding band.
• Right ring finger: to distinguish the PACS from a wedding to come, or out of habit in some countries.
• Another finger: middle or little finger, if the ring gets in the way at work or you'd rather wear it differently.

If you marry later, your PACS ring can stay where it is, switch hands or be worn with the wedding band. Traditions in detail: which hand to wear your wedding band on?

How much does a PACS ring cost?

At Laveran, a PACS ring costs from €90 (925 silver band) to €880 and up (lab-grown diamond solitaire). No budget is expected: choose what feels like you. Starting prices as of October 2026:

At Laveran, platinum costs the same as 18k gold. For a more visible diamond, the 1-carat Montaigne solitaire costs €1,744 in H/VS2 quality. Installment payment is available with Alma, and engraving is free.

Which PACS ring for a woman?

The two most common choices are a diamond half-eternity band and a small solitaire, in 18k gold. Start from the jewelry she wears every day: the gold color she already wears, and whether her pieces are discreet or bold.

• The half-eternity band, slim and luminous, worn alone or later with an engagement ring: the Saint-Louis from €536, the Vendôme from €696.
• The small solitaire, for a real symbol: the Montaigne round from €880 with a 0.30-carat diamond, or the heart version at the same price.
• The gold band, for a very understated women's PACS ring: the Fidélis also comes in a 2 mm width, from €320.

Yellow, white or rose gold? Yellow gold is warm and classic, white gold and platinum brighter, rose gold softer. All our lab-grown diamond half-eternity bands.

Which PACS ring for a man?

For a man, the usual choice is a plain band in 18k gold or platinum, 2 to 3 mm wide. It should be comfortable enough to wear every day.

• Fidélis, the classic band: €90 in 925 silver, from €320 in 18k gold or platinum.
• Jonc Parisien, more rounded: €90 in silver, from €400 in gold or platinum.
• Trianon, three slim interlaced gold rings: from €740.

Which width, profile or metal? It's all explained in our men's wedding band guide. The full collection: men's bands.

Which PACS rings for a couple?

For a pair, combine a diamond half-eternity band for her and a gold band for him, in the same metal: from €856 for both (Saint-Louis €536 + Fidélis €320).

• Small budget: two Fidélis bands in 925 silver, €180 for both.
• Two identical gold bands: two Fidélis bands in 18k gold, from €640 for both.
• The diamond pair: Saint-Louis half-eternity band and Fidélis band, from €856.
• The matching pair: two Trianon bands, with their three interlaced rings.

To link the two rings, engrave the date of your PACS, your initials or a word of your own: engraving is free. Ideas: what to engrave on a wedding band?

When should you order your PACS ring?

Allow 2 to 3 weeks: every ring is made to order, in your size. So book your appointment a month before the date of your PACS. If time is short, some designs are in stock and others can be made express in a few days. For a ring to give at Christmas, order before the end of November.

• Size: ask for our free ring sizer, or have your size taken at the showroom. All the methods: how to measure your ring size.
• Delivery: free, insured and hand-delivered, or pick-up at one of our 11 showrooms.
• After the PACS: free resizing for life, free polishing and prong checks for life, lifetime warranty and returns within 30 days.
