Jewel

Jewels are precious stones that appear in Castlevania. In earlier games, they were items to be sold at shops. In Castlevania: Symphony of the Night, they were bound to Salable Rings and were the only items that could be sold. They were also salable in Castlevania: Harmony of Dissonance. In Castlevania: Lament of Innocence, the jewels normally had no apparent function (they were sold at half their purchase value like every other item), but they had a power that could be released when destroyed using the Jewel Crush item. In Castlevania: Order of Ecclesia, the Jewels themselves had no abilities, but they could be given to Laura the Jeweler, who could make available Rings of that Jewel type.
