A one-of-a-kind ring featuring diopside in rose quartz. Fine black diopside forms delicate patterns within the softly pink-toned rose quartz, creating a graphic expression reminiscent of ink splattered across the surface. The vivid contrast between pale pink and black stands out beautifully against the stone's gentle luster, making for a distinctive and captivating piece.

The warm, antique-like tone of K18 white gold blends softly with the pale pink of the rose quartz, while complementing and bringing out the graphic patterns created by the black diopside.

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.
