Vintage metal alloy bracelet, probably pewter, with niello enameled engravings representing two facing snakes. Although bracelets similar to this one appear in the networks as from the firm Kirk Stieff the S within a rhombus is not characteristic of that firm and they are probably pieces from the mid-20th century (approximately the 60s) manufactured in some Asian country for distribution around the world.
It has normal signs of use, such as a little wear on the niello in some area and one part darker than the other, but it is in good condition (see images).
The metal is NOT gold or silver, so it can cause allergies if it comes into contact with the skin.
The images are part of the description (Neck base not included)
Attention: The material is not gold or silver so it can cause allergies.
