Justin K Prim 💎 The Gemcutters Craft 💎 Magus Gems

Hello and welcome to my channel. The videos you will find here are an expression of my passion for the art and science of gemcutting and the history behind it. Watch as I uncover the secrets behind the gem cutters craft as well as dive deep into the machines being used to cut gems around the world.

Currently, my scope of research begins in Europe in the late 1300's and extends all the way until now. As the channel grows, you will hopefully find a healthy mix of instructional faceting videos (reflecting my role as faceting teacher at the Faceting Apprentice Institute), gem cutting gear vids (reflecting my role as a gear nerd), gem analysis videos, and history-based videos (reflecting my role as a history nerd).

I hope you enjoy the videos and find what you're looking for. If I've left a question unanswered, please leave a comment and let me know. If you want to follow me in other places, click the social media buttons on top.

The Tucson show is almost here! I’ve got a packed schedule this year. I’m presenting two new talks plus an old favorite and I’m also participating in two panel discussions. In between all that, I’ll be at our booth (F2) at the 22nd street show with Facetron and Oak and Stone school. I’ll have books, lapidary stickers, and maybe even some new t-shirts. Come say hi!

Today is my 12 year anniversary as a gemcutter. The first stone I ever cut was a jade cabochon. Someone at the San Francisco Gem and Mineral Society (my local lapidary club) gave me the jade and showed me how to use the cabbing machines. This is the day that I entered heaven and I’ve been excited ever since.

I just published Episode 37 of The Gemcutters Craft podcast and today, we’re talking to gemcutter and shop owner Bruce McLellan about Canadian gemcutting, running a rock shop, and making his own hand faceters to help people get interested in the art of faceting.

Bruce runs a lapidary shop called Mountain Gems in Barnaby BC, near Vancouver. I had the chance to visit him at the shop in 2022 to talk about how he get into the faceting community, what the rock hounding scene is like in Western Canada, how he started making his own entry level faceting machines and eventually how he opened his own own rock shop.

The podcast is only available to my Patreon subscribers, so if you'd like to listen to this episode and 37+ hours of previous podcast interviews, you can sign up for only $3/month at the link below.
