of Korea.
This gold headdress is from independent
nation of Korea in the period of the Three Kingdoms - Baekje (백제),
Silla (신라)
and Goguryeo (고구려). The Three Kingdoms period lasted from 57 BC to 668 AD.
The gold headdress on the photo is
the enduring monument from Three Kingdoms period of Korea, found in a Large
tomb mounds. This headdress represents the crown made especially for burial.
Crown is made from thin cut sheets of gold and wire on which are added
coma-shaped ornaments of green and white jadeite.
