Sharbat Gula's Shawl

Origin
Sharbat Gula was twelve years old in 1985 and fled to Pakistan to escape Soviet fighting in her native Afghanistan when National Geographic photographer Steve McCurry found her and took her picture. She wore a red shawl over her head while she looked back at the viewer with piercing sea-green eyes. Early attempts to find her in the 1990s proved unsuccessful until she was found in 2002 and confirmed her identity through iris recognition.

Effects
Worn on that famous day, it didn't become an artifact until much later, long after the picture had become famous. Able to allow the wearer to emit emotion through the eyes, it can make others feel extreme amounts of empathy with the wearer. When affected, the user's irises will momentarily turn sea green.
