This is a vintage piece, which has been worn and enjoyed. There will be all of the the expected surface scratches and tiny dings in the silver from normal wear. The thick ring remains round and true. Hand polished, but there may be areas missed. This is a handmade item which will not be perfectly symmetrical nor machine-perfect in any other sense.
Killer piece of Mexican modernist jewelry. Thick and heavily crafted. This is very much a statement ring.
