"Chancellor Gorkon's necklace - Klingon-style necklace of cast metal with chrome plating. Made for David Warner as Chancellor Gorkon in 'Star Trek VI' and meant to capture 'a refined version of Klingon barbaric splendor,' according to Christie's. $400 to $600."
You mean David Warner didn't get to keep it? ;-) (It was probably the most attractive part of his costume, don't you think?)
