Oh, I forgot to mention the the necro and I made 12 plat each in 2
hours. :)

The first ring you can make to sell to players (you can't make ANY money
selling back to vendors, maybe with a CHR of 110) is the Jaded Silver
ring, enchanted silver + jade. Jade is approximately 3.7 plat each, the
silver is approx 6 gold. Selling price will depend on your customes, of
course, but start at 10 pat, see if you can get it. I've got a fairly
steady clientele where I am, and with a jewel craft of 32, succeed at
making jade rings about once every 3 tries, so even selling for 7
apiece, I'm STILL losing money. But every little bit helps. Rumor has
it that at Jewel Craft 40, Jaded Silver rings become trivial to make, so
that may help out then.
