Hello, I'm going to show you how to make tons of gold in WoW with two professions and little work - Jewelcrafting and Enchanting.
*Note* - This should work on most servers, if the prices for Lesser Celestial Essence is higher than 50% of the price of a single Carnelian then this will work.
Requirements - 475 Enchanting, 460 Jewelcrafting.
First of all, you need money to make money. Don't expect to invest 10g and come out with 10k the next morning. I invested 1.5k into this and within 24 hours I already have a 3k profit with more items still to be sold on the Auction House (2k worth).
You are going to want to buy out all Carnelian on the Auction House (Aslong as the price of Lesser Celestial Essence is no less than 50% of the price of a Carnelian) and then for every Carnelian you have bought buy a Jeweler's Setting from the JC Vendor. Make as many Carnelian Spikes as you can (These require 3 Carnelians and 3 Jewelers Setting each)
Once you have these made, disenchant everything. You should get 2-3 Greater Celestial Essences for every Disenchant, or from 2-5 Hypnotic Dust (you may loose a very small amount of gold everytime you get dust as an outcome, but this is rare and the essences will pay back for it greatly.
The final step is obvious - Sell all the enchanting mats you have gained! If you followed the instructions right this will normally generate a huge income of gold. Thanks for reading, have fun making your gold!And Merry Christmas to everyone that makes up one great and friendly community! Thanks for everything!
