Siam jewelry uses a technique called Niello a combination of copper, silver and lead sulfides used in an inlay on engraved or etched metals. Most of it was completely hand made. Nielloware jewelery and related items from Siam (Thailand) were popular gifts from american soldiers who were taking R and R, to their wives or girlfriends back home from the 1930's - 1970's and tourists bring home souvenirs and gifts from extended vacations and trips abroad during this period.
