Hmm, well, I think the easiest conversion would be 500 gems = $5, so 1GT per 100 gems? KS is a bit trickier, but feel free to offer what you think is fair? As for prices, I'd be happy to go with whatever the lowest on the AH is for whatever you're interested in (depending on what it is, I might be willing to take a little lower). As for the value of treasure, it looks like it's currently sitting around 1g:850t?
Alternatively, I think you have a general idea of the things I love from your pets (-coughKuhnascough-), and I'd definitely be willing to overpay in treasure/familiars/etc. for those guys. o3o
