First of all crafting isn't an easy skill on 562's unless owner has changed the experience rate. All of your crafting should be gems I'll get pictures up as soon as I can but for now I'll just write it out.
To start spawn yourself a chisel *1755* than go ahead and spawn yourself 27 uncut opals *1625* which will get you to the point that you can do sapphires so start spawning sapphires *1623* (27 opals may be enough for emeralds but not 100% sure have to check when server is back.) Than just keep going with your gem cutting from Sapphires-Onyx I'll list all the codes don't worry this guide is VERY basic for now seeing as I can't take any pictures of what I'm talking about this along with my woodcutting/firemaking guide will be updated shortly.
