It is a very cute, tiny, tiny 18k Gold St. Sebastian Medal made of solid 18k gold.
I picked these up in Rio de Janeiro, Brazil. They are nicely detailed and a great addition to your charm collection.
Measurements for this oval medal are 14mm tall, including the bail by 6mm at the widest point.
The approximate weight is 0.3 grams.
Clearly marked 750 for 18k yellow gold, each was carefully tested. They are new, never worn.
In Brazil, St. Sebastian or São Sebastião is the patron saint of the city of Rio de Janeiro.
