What quest on HorseIsle pays the most diamonds

Pyramids have the most diamonds along with other gems, so do the statues around jungle, but the best quests to do are pirate quests. Silver Mary's big production gives you two diamond necklaces and same with Edgar's missing friend. (he is located on the west bone thing of pirate, under the light house, between the sea and the palm trees.) there are 3 mini quests in this one but the reward is about 4 diamond necklaces.
hope this helped a little :)
