This silver ring is a faithful reproduction of Sayaka Miki'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. Color may vary a little from ring to ring.
This ring is sized at a 15 in the Japanese ring sizing scale, which roughly equates to a size between a 7 and 7.5 in US ring sizing.
