The semi baroque blue-gray pearls from Uwajima are all different and unique.

Because the world is full of colorful people,

by crossing, we can feel to know “myself” by feeling “different”.

This collection was created by providing pearls from Doi Pearl Farm in Uwajima, Ehime prefecture in Japan.

Matte finish on the sides

Matte texture and blue-gray Akoya pearls.

These two are an excellent combination.

In addition, the mirror finish on the thick part and the matte feeling on the sides create a contrast.

The contrast between the 9mm pearls and the slender ring arms highlight the sphere and its lines.

Uwajima Pearls

These Akoya pearls cultivated in the sea of Uwajima.

All of those pearls may not be perfect spheres.

even if they have some flaws, their pearls shine the best.

Each pearl is created by hand by our craftsmen according to the shape of the pearl.

To be completed the ring, it is necessary to adjust the ring according to the different shape of each pearl.

These beads are fascinating because they are not suitable for mass production.
