In view of the economic context and the soaring price of gold (+60% since 2020 and +26% over 2024), and because our relationship with you is based on values of transparency, we wanted to inform you of the increase in our prices from October 15, 2024. But we want to reassure you: the prices of our creations will not follow this curve, but will undergo a slight adjustment of around +10%.

Until then, and to benefit from our current prices, we invite you to :

- Make an appointment in our boutique or on video to obtain a quote at current prices (valid for 1 month).

- Anticipate your Christmas gifts by placing an order on our website before October 15.

Because you are our most loyal ambassadors, it was important for us to inform you and share with you, through an article, what lies behind the price of a precious jewel.

secretly dreams of this creation. It would be such a shame if you never knew!

We offer you 3 different methods to know your ring size from home. If you are still hesitating between two sizes, we advise you to take the larger one. Fingers can be more "swollen" at certain times, for example at the end of the day or in summer. Also, for your comfort, it is better to wear a ring that is a little too big than too small.

If the size of the jewel does not suit you, exchanges and returns are free and easy: we take care of everything! Resizing is also possible on some of our collections.
