I have been researching alot about making gold with JC and have noticed that nearly all the guides involve using enchanting to de rings, necks ect.
So I have decided to put this guide together for people who don't have the time or gold to level up Enchanting and only have JC!
First of you will need to buy as much [Ghost Iron Ore] as you can afford but leave some gold to purchase [Jeweler's Setting].
Once you have all your ore you are going to need to prospect this which can be a daunting task thats why I use a addon called panda which you can download from curse.com.
Ok now we have prospected our ore we have a bag full of gems and [Sparkling Shard] First off click all of your sparkling shards to turn them into [Serpent's Eye] you will use these to make ilvl 450 rings and necks. Now go to your local auction house and search for your rare quality gems like [Primordial Ruby] to see which cut is selling the best.
I recommend cutting the top three cuts so you don't flood the AH with one cut (Make sure you save some rare gems to make 450 ilvl pieces later), Now depending on how much ghost iron ore you bought you should have quite a few cuts from your rare gems and now its time to move onto the uncommon gets like [Pandarian Garnet].
With the uncommon gems do the same thing you did with the rare gems but this time only look at the "Perfect" cuts and cut the top three "Perfect" cuts. When you cut a gem their is a chance you will get a "Perfect" cut but not all the time so the gems you cut that are not perfect just vendor for a couple gold!
Well their's the gem cutting stage out of the way you are done with cutting gems!
Now to make some ilvl 450 gear!
Using your left over rare quality gems and uncommon gems see what rings and necks you can make, For one ring or neck you need 6 Serpents eyes 1 jewelers setting and whatever gem you need for that piece. To find out what rings or necks are selling good on your server go over to www.wowuction.com and choose your sever and choose Jewelcrafting as the profession this will show what is selling the best on your server.
On my server [Roguestone Shadowband] and [Golembreaker Amulet] sell well most of the time so I make more of those than I do the other pieces. After using the rest of your gems to make ilvl 450 pieces you can go to your local auction house and list them all up.
I use a addon called auctionator to list my auctions as all you have to do is drag your item onto the Auction House and it will price it and undercut your competition by one or two silver, Another awesome feature in this addon is under the more tab where you can check for undercuts on your items and then spam one button to cancel all your auctions that have been undercut so you can re-list them.
It can sometimes take a few days to sell everything you made so be patient and keep on re-listing but once you have sold everything you have a few more gold sitting in your bag!
