Uncut Goshenite Tradeskill Recipes for 300 - 350
Uncut Goshenite are one of the many different gems added into the game during the Prophecy of Ro expansion and have an extremely low chance (probably around .05%) of dropping off basically any enemy in the game 30 - 90. Due to this, farming a specific location for this gem is impossible.
If you play more than one character or for some reason think you'll need to raise Jewelcrafting in the future from 1 - 300 keep Half-Moon Cut Goshenite in mind. Or, do yourself an even larger favor and glance over my 1 - 300 Prophecy of Ro JC guide for a list of all the cheapest recipes you can do 1 - 300. All of the recipes mentioned on that page we're going to need to complete anyway to reach 350.
