Conceptual Jeweller. Founder of Urban Sterling.

This channel explores the materials science and craft behind jewellery; alloy science, gemology, and the engineering / design decisions that determine whether a piece lasts decades or fails in a year.

The jewellery industry is surprisingly opaque. These videos break down how different metals, gemstones, and designs actually behave, separating consumer-grade jewellery from heirloom grade objects.

Gemstone tier list is done, but my PC is so unstable that I can't export it lol. Getting a new one ASAP.

I heard you guys loud and clear. 18 minutes of gemstone tier list coming up, hopefully early next week.

I might have to dip for a couple weeks after this to go actually do my job and make rings, but for now I’ll try get this finished 🥹

Sidenote the server should be fixed now if you want to have a look at the site. Let me know if there are any problems

Hey everyone! Big thanks for all the support on the recent video, I never realised people were this interested in alloys and jewellery engineering lol. The website is getting absolutely hammered and my server is not having a fun time. Currently working on upgrading it though so it should be a lot faster soon.

I don't think I'll be able to make another long form for a little bit since I'm primarily a jeweller, I'll always prioritise the craft for my clients over the content, but I wanted to drop a poll here for the next video topic when I have some time. Which would you rather see next?
