Here's what's coming up over the next few weeks: First, Open Hours this weekend [...]

Ring Sizing, Simplified: Getting the Fit Right | Colleen Mauer Designs

Ring Sizing, Simplified: Getting the Fit Right

One of the most common questions we hear is simple: “What size should I order?” And the honest answer is — there’s a bit of nuance.

The Art of Ring Sizing (and Why It Matters)

Because CMD rings often feature nontraditional shapes like rounded squares — rigid squares, and sculptural bands — sizing can feel a little different than what you may be used to with standard circular rings.

 Every time I land in San Francisco, something in my body exhales. There’s a light that feels familiar and the smell of eucalyptus and sea water is so grounding.The fog rolling in over Twin Peaks feels like an old friend.

For International Women’s Day, we’re looking back at the girls we were, the women we’ve become [...]

Designing LP Giobbi’s Wedding Bands

Designing LP Giobbi’s Wedding Bands

When LP Giobbi asked me backstage at the Fox Theatre if I would design her and Chad’s wedding bands, I was absolutely floored. Floored in the “hold it together, Colleen” kind of way. Internally, I was doing cartwheels. If you’ve been here a while, you know that LP and I first connected through music and mutual admiration. [...]

Handcrafted mixed metal CMD rings and bracelets worn together as everyday jewelry

A Case For Slow Jewelry in a Fast World

I believe in owning fewer pieces of jewelry and choosing them intentionally. The pieces worth keeping are the ones that feel good on your body, work with your real life and grow more meaningful the longer you wear them. I’m sharing why slow jewelry, thoughtful materials, timeless design [...]

The Elephant in the Room: Metal Prices

Gold and silver prices change constantly, and when your work begins with real precious metal, those shifts matter. I’m pulling back the curtain on how rising material costs affect a small handmade jewelry studio, why we save and recycle every usable scrap, and how the old gold sitting in your own [...]

What I’m Choosing to Say Yes to in 2026
