Out of 500 Big-Mouth Clams I got 12 Golden Pearls and 33 Black Pearls, which sold for about 6000g. That amount does not contain other pearls I obtained, nor does it include the gold I made from the Clam meat, which is needed by cooks to level up. A stack of meat can sell for even 100g if no one else is selling it.
A Big-Mouth Clam may contain:
- Golden Pearl
- Black Pearl
- Iridescent Pearl
- Small Lustrous Pearl
- Zesty Clam Meat
TBC, Wrath and Cata clams can give other pearls aswell, but they aren't as valuable usually.
It's a nice money maker because you don't need to be level 85 to farm these. You can bring a lowbie here and gain level ups aswell!
Not a fast seller
A word of warning though! Pearls do not sell fast. It may take weeks to get rid of all your pearls. But do not lower the prices unless you are being undercutted. When someone needs them, they will buy your pearls, even if they cost 300g each.
Where to farm?
I've found 2 places to be worthwhile. Sea Giants in Tanaris and Naga in Blasted Lands.
Tanaris
Tidal Strider

- Goblins and Gnomes have to swim here :(

There are other places aswell, and you may look for more by clicking here.
