A one-of-a-kind ring featuring "tube in kunzite". Kunzite is a relatively new gemstone discovered in 1902 in San Diego, California. To be technical, it is a variant of the mineral spodumene, the pink and purple variations of which are called kunzite, and in Japan it is the birthstone for September. We have carefully selected this stone with extremely high transparency—proof of good quality—with "tubes" (hollow line-shaped inclusions) enclosed in the crystal. Platinum-colored tubes trapped in a beautifully clear pale pink oval-shaped kunzite emit a sharp sparkle, producing a delicate yet deep glow in a very attractive stone. The two-tiered platinum setting is designed so that you can enjoy a view of the stone from the side as well, to take advantage of the transparency of the stone and let in the light. A special ring that combines softness and cool 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.
