This ring is inspired by the straight path that two people will take in the future. The plain material is classic and minimalist, yet somehow modern, in perfect harmony with the engagement ring. A single lab-grown diamond shines on the inside. The design is simple and easy to wear in every detail. For women, it is recommended to wear it with an eternity ring or engagement ring.

Handcrafted by artisans in Kofu, Japan.
