A well travelled and highly experienced self-starter, Justin has lived all over the world. He has worked in the arts, the jewelry trade, technology, graphic design, counseling, fashion design, audio engineering, customer service, and more. Justin considers himself a modern-day Renaissance man, a jack of all trades, who is interested in everything and wants to learn it all!

Justin has been working in the gem trade since 2013 as a gemcutter and teacher. He has trained around the world in various traditions of gemcutting and is currently working on several books about the history of colored stone faceting in America and Europe. Justin did his gemology training at GIA in London and Bangkok as well as AIGS in Bangkok. He taught gemcutting at the Institute of Gem Trading and taught Gemology at AIGS Bangkok before founding his own gemcutting school, Faceting Apprentice. He published his first book, The Secret Teachings of Gemcutting, in 2021. He also writes articles, produces videos, and gives talks about gemcutting history.

Other Projects:

Justinus Primitive

My solo musical project for the last 12 years, Justinus Primitive is vocal, and experimental. Using only my voice, I create textured loops of sounds and harmonies. I build up these layers to create experiences intended to take the listener to higher levels of consciousness.

Wave Decay Sonotorium

A sound/art installation, co-created with artist Katie Anderson. Set in the crumbling remains of a Scottish Victorian mansion, the Sonotorium is a bath of sonic sensation that uses pure tones and harmony to create an unusually peaceful ambience.
