The Tibetan Silver Earring is the seventy-fourth treasure that can be found in Uncharted 2: Among Thieves.
The Tibetan Silver Earring is found in Chapter 22 - The Monastery. The first of eight treasures found during this chapter can be acquired by approaching the sealed door to the left, near all of the gathered trucks. If the player looks at the top of the sealed door, a flashing beacon can be seen, which indicates a treasure is there. Using the pistol shoots the treasure down from its perch, and can be collected by walking up to the front of the door to grab it. Since the treasure doesn't contrast well with the snowy ground, it is best to look for the on-screen prompt indicating a treasure is nearby.
