Fabio Vanin, originally from Italy, makes a ruby gold ring in San Francisco, Nayarit, Mexico. He says that artisanal jewelry-making is close to extinction because most people prefer cheaper, mass-produced jewelry from well-known brands. “I make these pieces one by one. I do not use molds, I work directly on the metal,” Vanin says. “I do small series in which the pieces can be similar, but they are never the same.”
