A one-of-a-kind ring featuring the exceptionally rare natural glass "Cristobalite-in-Libyan Desert Glass," formed approximately 28 million years ago by the impact of a meteorite colliding with Earth.This extraordinary gemstone was created when the immense energy of the impact melted surface rocks, propelling silica-rich material into the air, where it rapidly cooled and solidified. While most Libyan Desert Glass exhibits a yellowish, cloudy appearance, this rare piece boasts remarkable clarity with delicate white cristobalite inclusions.The setting features large slits that allow ample light to pass through, enhancing the warm transparency of the natural glass with an even softer, radiant glow. With its smooth, luminous presence, this ring adds a distinctive and elegant touch to any ensemble, perfect for everyday wear or special occasions.

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.
