This is a rare pendant signed by Hemmerle. It was made in the 1970's and the main feature is the use of a rough emerald set with pave diamonds and calibre and cabochon sapphires. The use of rough gemstones was very popular during the 1960's-1970's.
Hemmerle is one of the last family owned traditional jewellers surviving today. The two brothers Joseph and Anton were appointed purveyors to the Bavarian Court in the XIX Century. Later, in 1904 they opened a shop in Munich focused on traditional design but of exceptional quality. Today the firm is run by the fourth generation who has resisted the temptation of industrial manufacture and brand globalization.
The pendant will be auctioned by Sotheby's Geneva on May 17th, although it is not an expensive jewel it should be a treasure for collectors for its scarcity.
