A one-of-a-kind ring featuring a rare fire agate with a beautiful expression like a burning rainbow trapped within. Agates are found all over the world in various colors, but high-quality fire agates with vivid colors originate only in certain areas. The stone we have carefully selected for this piece shows breathtaking iridescence (an optical phenomenon in which minerals shine in the colors of the rainbow) interwoven within the deep brown mother stone, changing its expression with each angle. The soft blue-green base colors of the iridescence are reminiscent of the scenery of a rippling river, the gentle sparkle accentuated as if by a frame in the classic 18K gold setting. The matte texture of the ring, which looks simple at first glance, is made of countless delicate lines woven together. The ultra-fine lines, about the width of a single hair, spread softly and radially like the light emitted from a jewel, further enhancing the brilliance of the stone. Inspired by the beauty of nature and imaginatively united with delicate handiwork, this ring exudes joy with an air of dignified elegance.

Resizing at the time of purchase

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.
