ABOUT

Making the moments of putting away and caring for your jewelry as beautiful as the time you spend wearing it.
We operate the jewelry box brand "sentoujours." and the jewelry care brand "Amau".


Mission

Beauty, in every moment.
Beauty in every moment of your daily life.

The time you spend putting on, storing away, and caring for your jewelry.
May each of these moments become a time to cherish yourself.
We will continue to propose a lifestyle that lets you shine true to yourself.


Message

When you pick up a piece of jewelry, your heart suddenly feels brighter.
The small light shining at your neckline or fingertips gently gives you courage.
We wanted to deliver that feeling,
even during the times when you are not wearing it.

The moment you open the box.
The time you spend putting away something precious.
The time you spend carefully caring for each piece.
Even in the ordinary moments of everyday life,
you can create moments that make your heart feel a little brighter.

We believe that the accumulation of such small moments of excitement
leads to cherishing yourself,
and eventually becomes a radiance that is uniquely yours.

Through craftsmanship,
increasing such moments in everyone's daily life.
That is the future we aspire to.

Just remember your light.
May you always remember the light within you.

Jewelry has a way of bringing light to everyday moments.
We believe that feeling should live beyond the moment you wear it,
in the way you keep it, care for it, and return to it.
Through thoughtful craftsmanship,
we create small moments of beauty that inspire you to cherish yourself and what you love.
Just remember your light.
