Collecting guarded treasures

I've been going to a few Guarded Treasure locations marked by treasure chest and a skull. After I defeat the monster and collect the treasure, the chest/skull icon turns from white to gray and another icon appears in white that looks similar to an urn. What is this? Did I not pick up something? What am I missing here? Thanks gang.

I have used that item, but nothing speciall happend, does a quest start or something or what?

I have the lantern and I'm using it at the site. A ghost appears with a pick digging at the ground but nothing else appears. Clearly, I'm missing something here.

You're not missing anything, it's just a hint to say, look behind this rock - as it's an illusion.
