A one-of-a-kind ring featuring marcasite in quartz that contains an elegant and deep sparkle reminiscent of metal foil. Marcasite is a crystal formed by the combination sulfur and iron ore that becomes trapped within transparent quartz as it forms, producing marcasite in quartz, an ore created by several coinciding natural phenomena. Geometric marcasite trapped within the highly transparent quartz creates a beautiful piece showcasing the uniqueness of natural gemstones. The setting with a plain matte texture accentuates the charm of the stone from the top, while the prongs holding the stone alone have been given a glossy finish, giving the ring an elegant expression. The size makes it easily incorporated into your daily outfits, adding a stylish glamor to your fingertips.

Resizing at the time of purchase
For rings over ¥33,000 (tax included)
We offer complimentary resizing within ±3 sizes from the size in stock. If you wish to have your ring resized, please proceed to the purchase screen of the item and enter the desired size in the remarks form in the shopping cart. Production period: about 4 weeks
For rings under ¥33,000 (tax included)
We do not accept resizing from stock items. Please contact us using the inquiry form and we will make a custom order in the desired size. Production period: about 5 weeks
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.
