A one-of-a-kind ring featuring a high-quality, highly transparent bicolor tourmaline. The hazy gradation of cool-toned color appears gently shaded in like bleeding ink, giving this piece a soothing presence. The square-cut tourmaline, with its eye-catchingly clean, vertical form, is set simply in a frame setting and four prongs, nestled in a clean-cut matte platinum shank. A ring with a dignified presence that adds a touch of elegance to your outfit. Tourmaline, a popular birthstone for October, makes this piece a perfect personal talisman for those born in October.

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.
