I see I’ve got a lot of visitors over the last day or so from here. The author of that post has come up with a simple but interesting datamining idea – producing a consolidated list of the most popular gems to aid people playing the AH.

Unfortunately it isn’t really correct to add the percentage values in my tables since they are relative measures designed to show what is popular by spec. But the population in each class/spec combination varies wildly which make it impossible to go from that to a general count.

However, your humble dataminer stands ready to help with questions like this. I ran a query on gems across the overall sample and came up with the following list. The numbers are the total count of each gem and for comparison’s sake there are 171,148 characters in this sample who have at least one gem. I’ve chopped the table off at 5000, but the list goes all the way down to various cuts of shattered and opaque Dark Jade which are worn by one toon only in the sample.

Be aware that this is not a random sample – it is biased with a lot of higher level twinks, who could be expected to be gemmed up to the gills. But since twinking players are ones most happy to splash the cash, maybe that is no bad thing.

Let me say I’m right with you on questions about the WoW economy. The AH is one of the more inspired minigames in WoW. It’s a sort of non-zero-sum PvP where skill actually counts for something and you can’t twink your way to stardom. Even with Auctioneer, you still have to think about what the data is telling you. So, I’ve added consolidated reports to my to-do list. Anybody with other suggestions for reports that have an economic focus is welcome to leave a comment.
