The Shining Hope

"The Shining Hope" is the name of the engagement ring crafted by Jack Dinsdale for Potamos out of the synthetically grown Ginzuishou created by Hazel Ninegate out of a shard of Chibiusa's Mirai no Ginzuishou. Despite its size, due to the fractal nature of the crystal, it still possesses the ability to translate will to reality, albeit on a much smaller scale. In theory, any of the smaller facets could be used as a seed crystal to regrow a full-sized Ginzuishou.
