A one-of-a-kind ring featuring a geosite-in-amethyst. Within the soft purple crystal, orange-brown inclusions fan out like delicate feathers, creating a miniature landscape with a sense of depth. The ring is crafted with a slim, refined line that naturally blends into everyday wear, adding a quiet touch of individuality to the fingertip. It feels like wearing a gentle glimmer close to the skin—a small landscape to accompany your daily life.

Selecting your ring size

We recommend choosing a size that you can comfortably wear without feeling pressure or tightness when you make a fist, and without discomfort between adjacent fingers.

For wide rings of 6.0 mm or more
Compared to the number measured with a typical ring gauge, a wide width ring may feel a little tight to wear due to its large surface area. When considering a wide ring, we recommend that you choose a slightly looser size than you usually wear, 1 to 1.5 sizes up.

Please note that some rings cannot be resized due to their design.
Please check the details on each product page.
