A one-of-a-kind necklace featuring moss aquamarine in an eye-catching light blue color. This rare natural gemstone contains a titanium-iron oxide liquid inclusion, called ilmenite, trapped within the aquamarine. A piece with beautiful moss-like inclusions and sparkles like metal fragments that appear to float casually within the clean square form. The setting and prongs in a plain matte texture have been designed to bring out the charm of the stone, imbuing it with a simple yet subtle individuality in harmony with the form of the stone. Its size makes this piece easily incorporated into your daily outfits, yet with a strong sparkle and a chic atmosphere.

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.
