A one-of-a-kind ring featuring calcite in quartz, the result of calcite—a mineral of crystalized calcium carbonate whose name comes from Latin—becoming enclosed within the quartz as it develops over time. The quartz is highly transparent, and the cuboid calcite crystal trapped within stands out clearly in the glossy cabochon shape, a beautiful stone we have carefully selected for this piece. Delicate linear rutile crystals that run randomly in all directions, and the calcite that appears to flicker between reality and imagination, are enclosed together in the quartz, creating a geometric, three-dimensional structure, like a fleeting moment of movement frozen in time. A piece with a quiet, refreshing beauty. A voluminous stone with a wide surface area tends to shift when worn due to the delicate ring shank, so we have made careful adjustments in 0.1mm increments in the design to optimize comfort for the wearer, balancing strength and lightness. A statement piece of mysterious beauty, as the calcite appears to float in the air within the quartz. A ring with a bold presence and a cool impression.

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.
