Story of RADIANN

In English, “Radiant” (ラディアント) means

to emit light, to shine, or to be bright and cheerful.

ー Radiant smile a radiant smile
ー Radiant with happiness shining with happiness

Not only in relation to objects, but also to people

it expresses an inner beauty that shines brilliantly.

When Aya, the founder of RADIANN, encountered this phrase

she was struck in her childhood while living overseas, thinking, “What a beautiful and wonderful word to express a person’s radiance,”

and that experience became the inspiration to launch the RADIANN brand.

There is also a diamond cutting technique called the “Radiant Cut,” which is loved by people around the world.

The very first piece of jewelry made on our founding day—the Radiant Cut, Aya’s talisman of happiness—

forms the R in the RADIANN logo.
