Guaranteed money with Jewelcrafting.

You have Jewelcrafting at skill level 350 and want to level it higher and make money?
Here's a little trick.

You will need:

• Huge Citrine, Sun Crystal or Bloodstone for 1g or less each
• Eternal Earth for 5g or less each

You are gonna make:

• Sun Rock Ring, Crystal Citrine Necklace or Bloodstone Band

Why these?
Let's do some math. Mats for each are 1 gem and 2 Crystallized Earth (5g/5 = 1g per 2)
If you get these mats for the prices I listed the costs will be 2g per Jewelry, but look at the vendor price, 3g14s wich is 1g14s per. This is always guaranteed money unless your vendor doesn't like you anymore.

Sell-O-Matic.
Download this addon: http://wow.curse.com/downloads/wow-addons/details/sell-o-matic.aspx
Now go to Esc > Interface > Addons and click Add item and add the items there to auto sell them to a vendor. Craft you bag full, open a vendor and auto profit :)

With a big supply of gems and Eternal Earth you should be able to make atleast 500g per hour.

Goodluck
