diablo-3
I thought I might get lucky with some vendor for jewelry, as I did not find any way to craft rings and amulets.
I tried Litton the Fence in Act IV Inferno, but basically he sells shitty items. Mostly blue items at level 55 or less.
What is the vendor with he best jewelry in the game and what kind of items does he sell (level, number of attributes etc.)?
Is it actually possible to buy rare level 59 or 60 jewelry?
Watch the auction house.
Right now, crafting materials are selling for substantially less gold than all but the worst low level blue items. You'll get far better results selling your blue items and buying Essences from the AH.
For example, current market value for normal mode mats is 20g for Subtle Essence and 45g for Fallen Teeth. So any item worth more than 25g, I sell. If its worth less than 25, I gamble for a shot at a tooth.
Diablo III has a handful of merchants, but for the most part, they are named for your convenience. Specifically, only merchants known as, "... the Fence" will sell you "Trinkets", which include both amulets and rings. They will show up on your minimap as "Fence".
Radek the Fence is in the Nortwest part of Tristram, on your way towards the Northwest gate.
Silmak is also chilling in the Northwestern part of the town, though in his case, he's overlooking the city, a little east of the healer.
Litton is hiding in the southmost part of the Worldstone Keep area, where he will sell you the belongings of dead soldiers.

Like Novarg says random merchant outside of town always have 1 rare item to sell. But....seriously....if you want good jewelry use Auction House has i don't see the chance of seeing a rare amulet or ring from a random vendor. That makes a low chances.
EDIT : To answer your comment i will redirect you here there's screenshot of every merchant in the game and their spawns should be good enough :)
EDIT 2 : Since patch 1.07 you may craft rare amulets at the Jeweler. You may find more info here
