Paleontologist Ron Ruschman cut gemstones after university, during a period spanning  the 1980s and 1990s now known as the Lapidary Renaissance; approximately 60 gems of which comprise the Lost Grotto collection.

Although Ruschman does not cut for Lost Grotto at this time, his incredible contribution warrants an honorary position on the LG design team.

Today, as a passionate paleontologist, Ron currently owns and operates The Muse, a dinosaur fossil museum replete with his personal discoveries,  including a baby T-Rex.
