This is quite a Unique pin, from the 1960's. Made of 14kt Gold (an extremely small mark on the inside of the pin clasp) set with 8 small Diamonds and 8 Teardrop shaped yellow Citrines.
Most likely created by a fine Jeweler, as a custom piece for a client.
The size is approx.1.75"long x .75"wide and in good condition!!...CA.1960's/1970's..in 14Kt with some very nice stones, and a goodly weight.
Quite attractive in an exuberant way!!....add it to your collection of Mid Century Moderne jewelry....
