So I spent some time in the past week looking for a guide to what the different colors mean and I did find one. I don't know if it has all the elements, but it does have a good list, so I wrote them down for later. I also went to the market yesterday to see gem prices and found that I wasn't that far off from my earlier guess. I'll take me around three more weeks to buy one and a few days to enchant and fill it.
