Swamped

You catch sight of something glinting amidst all the droppings. As you sweep them aside, it seems to be some sort of jeweled ring.

Oddly, it looks to be half-buried in the sand. Must have been there a while to sink that much, or maybe the sandrunners just kicked up a lot of it.

You clear out the area a bit more and reach down to pick it up for a closer look.

You can't. It's as if it's stuck... but there's just sand here. What's going on here?

Now you really want to know what's up with this ring. But how can you get it out?
