At the center, two large Romanechite inclusions appear to float, their softly defined contours clearly visible, evoking an elegant presence—almost as if they are whispering closely together. The meticulous craftsmanship extends to the ring's design, where the K18 yellow gold setting seamlessly transitions into a K18 white gold band with a smooth, subtle gradient—an exquisite detail that may not be immediately noticeable but adds to its charm. Amethyst, cherished as the birthstone of February, makes this an ideal and meaningful talisman for those born in this month.

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.
