Something I have found to be a decent goldmaker is Thick Felsteel Necklace. I can normally sell 1 if I list it for 48 Hours allowing me to sell about 3 a week, and I sell them at 75g Per and mats cost around 15-18g on my server which is a nice 55g profit.
Also on my server Epic Gems are Sell around 400g-450g Per except Green and Yellow gems which are around 300g. So if it is 10% for Brilliant Glass thats a nice little perk for JCing
