The Rio Grande Jewelry Tech Team

After nearly a century in the jewelry business, we've seen innovations that change the way we work, as well as plenty of techniques that stand the test of time. We've come across the trickiest technical challenges and the most elegantly simple solutions. And we've received the lessons of countless trials and errors along the way. When you've spent a lifetime learning, what do you do with all that hard-won knowledge?

At Rio, we believe in passing it on. And that's what our Jewelry Tech Team is all about.

Rio Grande is home to seven master jewelry technicians whose sole job is providing you with answers and expertise, free of charge. Together, they represent two centuries of hands-on knowledge you won't find anywhere else. It's the type of information that can only be passed from one jeweler to another—because it comes from experience.
