Hmm Doby's guide seems to make it seem like every gem, with the exception of the hp/s (rep locked) one, are available to f2p.I think they may not be avaiable to prospect to F2Ps, but should be able to buy them off the AH.
oh smart, ty!I'm guessing you need to be in SL chromie time for the nodes to be minable. If you don't have access to Chromie then need to party sync with someone on SL chromie timeline.
