This silver ring is a faithful reproduction of Madoka Kaname's soul gem. The position of the embedded gem, the detail of the pattern, and the three-dimensionality have been faithfully reproduced in the new design.
The main body is made of 925 silver, and the characteristic patterns are carved and then oxidized. The gemstone part is made of synthetic pink tourmaline.
This ring is sized at a 19 in the Japanese ring sizing scale, which roughly equates to a size between a 9 and 9.5 in US ring sizing.
