Nothing turned up in a forum search, but I thought I'd ask around before starting on one - are there currently any libraries which provide a database of gem info? Specifically, gem id, gem item id, gem stat names & values, gem color, component colors (for socket matching), etc.
See the tables in my Socket Master addon for an example of what I'm sort of looking for.
