The U-shaped nail used to fasten two building materials together, known as kasugaiStaple, has long been familiar in Japan as a symbol of connection between people and between things.

That structure has been applied to jewelry stone setting. The oval-cut natural stone is gently held in place by a kasugaistaple-shaped part. With this new stone-setting method that does not require traditional "prongs" or a "frame," the natural stone’s shape and character are able to breathe more freely.

This ring features lapis lazuli. The material is K10.(Size 10 / In stock)

The stone "lapis lazuli" is striking for its deep lapis blue color, and its name comes from the Latin word for "stone" (lapis) and the Arabic word for "blue" (azul). In ancient Mesopotamia and Egypt, it was prized as a "sacred stone" and was also used in Tutankhamun's mask. Its blue comes mainly from a mineral called lazurite, and gold-colored pyrite may float within it like stars. Its mysterious appearance, as if it has captured the night sky, has fascinated people מאז ancient times.
