A one-of-a-kind ring featuring a rare platinum rutilated quartz. Delicate linear rutile formed by growth of the mineral brookite is trapped within, its beautiful platinum color giving this stone its name. The formation of platinum rutile quartz requires several specific geothermal conditions occurring in only a few mines, making this rare gem the least-produced kind of in our collections so far. A high-quality stone of this kind with highly transparent quartz in beautiful balance with the color of the rutile contained within is especially difficult to obtain. After a long search, the designer was finally able to source this stone. This detailed and expressive crystalline structure appears like a fine cloth that has been painstakingly woven from threads one by one, a texture that is more enjoyable and satisfying the more you look at it. The yellow gold shank has been designed to accentuate the rutile that shimmers like whitish platinum. The setting firmly supports the stone, like a frame enclosing and protecting a masterpiece. The quiet passage of time is contained here to grace your fingertips.

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.
