Innovations In
Jewelry Manufacturing
and the Invisible Clasp

Original Airdate: Nov. 11, 2020


In this webinar, Andrea Hill speaks with Riva CEO Ted Doudak and Rebecca Doudak about a few of the company’s newest capabilities (in-house lapidary, hard enameling), as well as its latest innovation, the Invisible Clasp. Popular among manufacturers and designers looking for a clean, minimal look, the clasp can be used to close a chain necklace or bracelet, attach pendants, or stand alone as a pendant itself. Learn how this versatile component can add new flair to your designs, and how it furthers Riva’s goal of transforming a finding into a beautiful piece of jewelry.
