Mexican jewelry vintage ring "21"

This Mexican jewelry was made using a technique called Metales Casados, which means "mixing metals" in Spanish and was created in Mexico in the 1950s. The top features a sun motif, which is also often seen in Aztec ruins, and is thought to be made of crushed malachite, brass, and copper. This technique has already fallen into disuse due to its high cost.

The ring itself is made of 925 silver and is not too shiny, so it feels familiar to the skin. The size is 15, so it is OK for a man's main finger. "Mexico" is written on the inside, "APB" which is probably the designer's initials, and an eagle mark on the outside. From this eagle mark, we can guess that the ring was manufactured between 1955 and 1980.

Size: 15(JP), 7.5-8(US)
