Mexican jewelry vintage ring "22"

This Mexican jewelry is made using a technique called Metales Casados, which means "mixed metals" in Spanish and was created in Mexico in the 1950s. The top features a motif that appears to have been drawn by Mexican tribes, and we believe the material is crushed malachite, brass, and copper. The ring itself is made of 925 silver and has a slightly elongated design. It is sized at 15, so it can be worn on a man's main finger. The inside is engraved with "925BR" and "MEXICO".

*It can be worn without any problems, but there is some deterioration in the malachite part at the top. Please check the image carefully.

Size: 23(JP), 11(US)

Material: 925 silver, copper, brass, malachite (probably)
