The following is a list of unique jewels, items inserted into Sockets in Diablo II: Lord of Destruction. All unique jewels were added with Patch 1.10. All unique jewels go by the name of Rainbow Facet, but there are eight possible stats: two each for Fire, Cold, Lightning, and Poison. All Rainbow Facets cast a high level spell either upon leveling up, or upon death. Graphics of unique jewels are not fixed, and are randomly generated and assigned. Upon death Rainbow Facets can be particularly useful on hirelings who are very prone to being killed.
