I was so fascinated when I first saw this ring. I thought it was of Indian origin until my mom pointed out that it’s a “lansadera” ring. Apparently it’s a local vintage design that was very popular in the 1930s to the 1950s. “Lanzadera” is a Spanish word for shuttle, a boat-shaped piece of wood used as a device in the loom.
They normally have “diamante” or rough cut diamonds in them which were considered lucky in those days. The pointed ends make for good self-defense too. ;P
Here are some more designs:
These rings and even the earrings version normally come encrusted with diamante but I was able to acquire one that has pearls instead. Looks a little different from the ones I usually come across with.
These rings look like armor or knuckle rings that are very fashion-forward now.
