First off, Xornot's Gem Finder by Xornot of Gorefiend is an awesome little application that lets you browse through all the gems in the game (so far-- I'm not a jewelcrafter, so I don't know if it's completely up-to-date) according to socket color, stat bonuses, crafting or vendoring, and even by name. All of the gems are color coded, and because Xornot is apparently a l33t web coder, everything is Ajaxy smooth. Very cool tool for finding just the right gem for that shiny new epic you just picked up.
Jesta has also created a jewelcrafting tool that may not look quite as shiny as the first one, but in fact goes a little farther-- not only can you browse all the gems in the game (by base gem, color, or class appropriateness), but it looks like eventually, jewelcrafters will be able to log in, list the gems they can make, and even list prices for prospective buyers on the server. It's kind of like a custom online auction house listing for jewelcrafting. Unfortunately, there's no date listed for functionality, and it seems like Jesta is a little too busy working on all kinds of other things to get it up and running, but we'll throw a hug his way and thank him for the great online app.
The 2.1 changes will bring a little more order to the auction house in terms of gems, but until then (and even afterwards), these tools look really useful for both prospectors and their customers.
