Modern Goldsmith is creating beautiful + sustainable jewelry for lovely people all over the world. We blend traditional goldsmithing techniques with modern tools and materials.

Founded in 2016 by Jordan Mantzke.

Jordan is a goldsmith specializing in jewelry design, restoration, and custom-made projects.

His journey to becoming a goldsmith started in 2001, working his first job as a jewelry polisher. Spending time in a workshop made him realize just how much he enjoyed working with his hands in a creative field.

Over the years he trained under three master jewelers, working full-time as an apprentice until he had the skills necessary to go out on his own. Jordan started his own business in 2012, later adopting the name Modern Goldsmith in 2016.

Modern Goldsmith is currently based in Petaluma, California.

Shipping our jewelry worldwide to select countries.

The shop is not open to public. Visits may be permitted by appointment only.

Where the goldsmithing action is:

We are true believers. Lab-grown diamonds are conflict free, 100% identical (visually and chemically) to diamonds from the earth, and cost a lot less as well.

In 2016 we made the conscience decision to no longer sell or use mined diamonds in our jewelry. Instead, we are proudly focused on creating jewelry with lab-grown diamonds, moissanite, and other conflict-free diamond alternatives.

Jewelry drops, announcements, giveaways, etc.
