now that you have made the bronze bars, you need some garnets to make your new claw. finding the gem cave can be tricky - it is very easy to run right past it without realizing.
from the mws, go back down the hill to the road thru the cedars. you have already gone by the gem cave - it is right at the beginning of the sandstone field. so pass by the windmill and stay on that road until you emerge at the crossroads that indicate your arrival and the sandstone field. on your left should be the gem cave, unless you have gone to far. if you make it to the sws, you need to back up to the crossroads. once inside the cave, you head down a long corridor opening up onto a large cavern with gem nodes all over. this cave holds turquoise and malachite as well as garnet. the corridor you see in the middle right of the screenie leads to another cavern with rich and motherload nodes. activate your quarrying ability (you have them all hotkeyed by now, i am assuming) and get to work.
once you have dug up some raw garnets, you need to process, or cut, them. this requires a gws, or at least a gem cutting table. fortunately, there is one mere steps from the gem cave. exit the cave next to the crossroads. you should see the very top of the gws from the cave mouth. continue down that road and you will end up (literally, the gws is on the edge of a cliff) at the gem workstation.
you will meet some biped trainers hanging around the gws, but you need the machines inside the ws. step up to the cutting bench and activate your gemcutting ability. pull up your gem form and choose garnet, of course. once you have made your 12 cut garnets, your game log and quest journal update, instructing you to return to kerian for further directions.
tune in next time to find out how it all ends!! ;-}
