[Lumière] Half eternity ring 0.3ct

"Amber light, hidden in the everyday."

¥88,000 (tax incl.)

A half eternity ring set with 0.3ct of lab-grown diamonds in total.
Refined yet light to wear, it brings a quiet sparkle to every occasion.
Also recommended as a wedding ring.

“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.

[Our Philosophy]
"A lifetime piece should be an honest one."
With that in mind, we center our work on lab-grown diamonds, transparent in origin and lighter on the environment.

At the same time, we do not dismiss natural diamonds.
Stones the earth has nurtured over billions of years hold an undeniable mystery and romance.

Rather than declaring one correct, we see it as our mission to convey the value and the challenges of each honestly, and to offer choices our customers can truly trust.

Drawing on the latest knowledge from our base in Europe, we shape each answer with care. That is how we approach jewelry meant to last a lifetime.

Sizes are Japanese ring sizes. If in doubt, we recommend your exact size or half a size up. Ring sizer rental →
