Find your size.
Enter the world.
The size of a mood ring is measured in millimetres of circumference — not in diameter as in classic jewellery. It's better to choose a slightly larger size than your usual ring. The MULTISIZER ring sizer gives you your exact measurement on all your fingers — that's the foundation of everything. 🌸

How to find
your mood ring size
The size of a mood ring corresponds to the circumference of your finger in millimetres. This is different from the diameter used in classic jewellery. Two simple methods to measure at home.
Measure the inner diameter in mm. Multiply by 3.14 — you get the circumference = your mood size. Example: diameter 17.8 mm × 3.14 = 56 mm → size 56.
Wrap around your finger, mark the joining point. Measure the length in mm = your mood size. When in doubt between two sizes, always choose the larger one.
The Companion column shows the size to order for rings alone (without a mood base) — always 2 sizes below your mood size.

What you feel
this morning,
your ring says it.
We imagined a ring that isn't fixed. Not a single piece you wear by default every day — but a living object that evolves with you. Your mood, your season, your chapter.
The mood click is three seconds to change everything. And a mood collection that grows with your desires. 🩵
We imagined a system.
It won over 75,000 customers.
Mood Collection was born in Orbe, canton of Vaud. In a Swiss workshop, with jewellers, stone-setters, and one wild idea: an interchangeable ring that changes with you.
Twenty years later, the system is certified, the guarantee is for life, and over one million interchangeable rings have been sold. Not a trend. A Swiss collector's jewel.
Some bonds are
forever.
You evolve.
We used to think a wedding ring was chosen once and for all — one metal, one moment, one frozen memory. The mood ring thinks differently: a wedding ring that evolves with you, over the years.
Giving a mood wedding ring is acknowledging that two people in love will never be quite the same from one year to the next. The base holds the promise. The rings grow with you.
Surgical steel, titanium, 9K or 18K gold. Handcrafted stone setting in Switzerland. Lifetime guarantee. An emotional jewel that never dates — it evolves.

Everything about
the mood ring.
What is a mood ring?
A mood ring is an interchangeable jewel made of two elements: a base in 316L steel or titanium, lifetime guaranteed, and rings that click on in three seconds. You can change your combination endlessly — according to your mood, your style, your chapters. It's a personalised ring that evolves with you.
How does the interchangeable system work?
The mood click is our system developed by our Swiss house. You place the ring on the base, you click — and that's it. No tools, no soldering. The gesture takes three seconds and the ring is firmly in place. To remove it, the same gesture in reverse.
What makes the mood ring an emotional jewel?
An emotional jewel is one that says something about you — not a neutral accessory. The mood ring is designed to evolve with your identity: one ring for everyday, another for an evening, another for a moment that matters. It carries what you feel. That's why 75,000 customers wear it every day.
How do I find my mood ring size?
Mood bases come in sizes 48 to 60 for women, 58 to 70 for men. If you don't know your size, our in-store advisors can measure you in a minute. You can also receive our MULTISIZER ring sizer — free — to find your exact size from home.
Are mood rings durable and resistant?
Our bases are in surgical 316L steel or titanium — two of the most resistant materials in jewellery. Hypoallergenic, rust-proof, designed for everyday wear. The lifetime guarantee isn't a sales argument: it's our commitment to quality.
Can I personalise my mood ring?
Yes — it's actually one of our specialities. Through our configurator, you create a ring with engraved text, a symbol, a motif or a fingerprint (Digit collection). Available materials: 925 silver, 9K or 18K gold, titanium, ceramic, tantalum. Every personalised piece is handcrafted in our workshops.
Where can I find a mood ring in Switzerland?
Mood Collection has 6 boutiques in Switzerland: Orbe (HQ), Carouge, Martigny, Fribourg, Zermatt and Zurich. Our advisors welcome you to create your first mood ring. You can also order on yourmood.net — fast delivery in Switzerland and across Europe.
What is the difference between a mood ring and a mood wedding ring?
In reality it's the same system — the same interchangeable base, the same mood click. What changes is the intention and the choice of materials. For a wedding ring, you naturally turn to precious materials: 9K or 18K gold, tantalum, precious stones set by hand. Because a wedding ring carries a promise — and you choose a metal worthy of it. But the principle remains identical: a ring that evolves with you, over the years and the chapters.
Your ring,
entirely you.
Engraved text, symbol, drawing, motifs, colour, material — create a personalised interchangeable ring that reflects you. Custom band handcrafted by our Swiss jewellers. A unique emotional jewel to wear every day.
