Get easy gems.

[shadeburn]

If you are a Jewelcrafter in need of gems/money, instead of prospecting stacks of 20 ores, split the stacks to stacks of 5 ores, and when you prospect, you should get the same amount of loot from each of the small stacks, that you would from one big stack.

4 times more gems.

Combined with the trade soulbound exploit, you can equip all of your alts with gems thats better than BT gems very fast. (requires a friend, or 2 accounts.)
