A fishy little friend to liven up your favorite cardigan!

He measures 2-1/2" from snoot to tail and about 1-1/4" from top fin to bottom.

His amethyst cabochon eye is about 4.2mm in diameter.

Standard pin hardware.

Lots of stuff stamped on his back:

HECHO EN MEXICO (Made in Mexico)

[HALLMARK] (Francisco Rivera's hallmark: his conjoined initials in fancy script)

EMMA (Either a store or another wholesaler for which Mr. Rivera produced jewelry)

812 (Inventory or design number)

STERLING MEXICO

[EAGLE 3] (A Mexican registration system used from 1955 to 1980)

According to Hougarts, the marks on the back of this pin date the piece some time between 1953 and 1971.  

Mr. Rivera was a Taxco designer and silversmith who honed his craft in the workshop of the great William Spratling.  According to Hougart, "Francisco Rivera's distinctive style is characterized by bold designs manufactured of heavy gauge silver."

This pin weighs 16.1 grams.

Thank you for looking and reading this HUMAN-GENERATED description!  Nothing fishy about it!
