Ulmo and Aulë: Lazy, Busy, or Unaware

[The Perky Ent]

In 'Of the Voyage of Eärendil and the War of Wrath', we know that Maedhros and Maglor are the only living survivors of the sons of Feanor. After being convinced by his brother, Maglor helps Maedhros break into the camp of the Valar, and steals the remaining simarils. Maedhros can't take the burning the simaril causes him, and jumps into a fiery chasm, along with the Simaril. Maglor, on the other hand, throws the simaril into the sea, and 'he came never back among the people of the Elves'. Wether he is dead, or walks the shores forever singing tragic songs of despair is of debate.

Sorry for the little history lesson, but it's important to my topic (which I will now get to!). With that little recap, we know that the brothers couldn't take the burning of the simarils, and threw the simarils into the ocean and earth. According to Quenta Silmarilion, that's the end of that. But then I started thinking: "Wait a minute. The valar deeply wanted the simaril. And Ulmo is the God of the sea. And Aulë is that of land. Wouldn't they, as they were the masters of those elements, be able to reclaim the simarils? Ulmo could have spent his times underwater (since it is mentioned in the Silmarilion that he spends most of his time away from Valinor, in the oceans of Middle Earth) looking for the lost simaril of Maglor. It couldn't have gotten that far from the coast. Being the Lord of water, the Aquaman if you will, surely he could have found it.

And what about Aulë (Aulë didn't actually pop into my head until I had finished the first paragraph ). He is a master of the lands. Although he doesn't spend as much time away from Valinor as Ulmo, surely he could have taken the time to look for Maedhros' simaril. He couldn't have gotten that far from the camp of the valar, and a 'fissure' couldn't be that hard to find (especially for someone as powerful and well known as Aulë). So here is my question: Were Ulmo and Aulë too lazy to look for the simarils (ie they felt it was best just to leave them alone), too busy with their Valar duties to stop and look for the simarils, or were they just unaware of the first paragraph i wrote, and dindn't know of the simarils fate?
