A one-of-a-kind ring crafted with a rose-cut Galaxy Diamond that radiates a dense brilliance. Known as a "Galaxy" diamond, it contains intricate inclusions reminiscent of outer space, capturing light with remarkable intensity. The subtle play of shadows and sparkle within the stone shifts quietly depending on the angle, creating a mesmerizing effect. The ring is designed with minimal adornment to highlight the presence of the stone. A touch of hammering on the K18 yellow gold surface subtly preserves the artisanal texture. A unique, one-of-a-kind ring that holds deep radiance within its serene beauty.

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.
