[Lumière] Half eternity ring 1ct

"Lace of light, at your fingertips."

¥198,000 (tax incl.)

Lace of light, for your fingers.

One clear morning.
While designing, we simply placed diamonds on a finger.
In the morning sun, the stones sparkled like light at the water's edge.
We wanted to deliver that momentary brilliance just as it was.
This ring was born from that wish.

Ten 0.1ct lab-grown diamonds, generously lined in a row.
A shared prong setting brings out the full clarity of each stone.

The presence of a full carat, balanced to sit gracefully on the hand.
Worn alone or layered.
A ring like lace made of light, for everyday and for celebration.

“Lumière Collection”

Soft light filtering through lush green leaves, and the amber glow that slips through the window at dusk.
A collection of lab-grown diamonds inspired by the quiet light of everyday life.
