Have you tried the world bosses there? My impression was that they did drop jewelry. IIRC the last piece I needed there was jewelry and I got it from the Harvester boss.

Thought should be given to modifying drop tables in zones missing certain activities. Add jewelry to world bosses in Coldharbour, for example.
