In the chaos of everyday life, it’s easy to forget to celebrate the good stuff, the big milestones and even the little wins — but this year, we’re making space for all of it. CMD turns 20 this September, and while I’m still wrapping my head around this big milestone, one thing is for sure: I want to celebrate this year in a big way [...]

When I sit down at my workbench — usually with a fresh cup of coffee and a pencil sketch that’s already been lived in a little — I’m thinking about more than just metal and stone. I’m thinking about the way jewelry becomes a part of us. How a single piece can carry a memory, a milestone, or a sense of power that’s uniquely our own. I'm thrilled to [...]

CMD’s production studio is on the move… but we’re not going very far! Later this month, we’re moving into a brighter and slightly larger space just next door to our current studio in Trumansburg, New York (or as the locals lovingly call it, “T-Burg”). While our Upstate NY studio isn’t open to the public, it’s where all the real magic happens. Every single piece is [...]

As the year comes to a close, I’ve been sitting with a deep sense of gratitude and reflection. 2025 was a full year — creatively, emotionally, and energetically. It stretched me, grounded me, challenged me, and ultimately reminded me why I chose this path all those years ago. Here’s a look back at the year [...]

Friends, it’s almost here! This Saturday, October 4th, CMD officially turns 20 years old — and we’re celebrating with an unforgettable soirée in Asbury Park. The whole CMD Team is coming together under one roof for the first time in years, and we can’t wait to raise a glass [...]

The evening was filled with so many meaningful moments and the sun was shining on our backs on a very sunny fall afternoon. We shared laughter, hugs, stories, and a few happy tears as we looked back on the journey that’s brought CMD to this point. Guests sipped, stacked [...]

Every step of the CMD journey has been immensely rewarding, but there are certain milestones that make our heart sing oh-so proudly. Beyond being one of the most renowned places of modern design in Northern California, SFMOMA was an inaugural part in the creation of Colleen Mauer Designs.

Two full decades of making, learning, stacking, soldering, connecting, reinventing, and dreaming — all thanks to you. Whether you discovered CMD in San Francisco twenty years ago or stumbled upon us last week, you’re part of this story. And today, I’m thrilled to share something truly close to my heart. The Big Two-Oh Collection [...]

CMD is turning 20 this year! And now, for the first time in a very long time, our entire CMD team will be together in Asbury Park to celebrate this milestone with YOU. It's going to be a CMD reunion and anniversary party rolled into one. We’ll be showing off the CMD collection and we’ll have light bites and drinks so plan [...]

Friends, CMD’s 20th Anniversary Party is almost here and the nostalgia has really set in! I’ve been looking through old photos and reminiscing about CMD in the early days. That first leap of faith — saying yes to a studio I wasn’t sure I could afford — taught me something I’ve carried with me ever since: little risks open big doors. Every milestone CMD has reached since then has been built on that same  [...]

As I reflect on these 10 years of glory, pain, joy, tears, laughter, friendships, and oh-so much more, I must express both my gratitude and my nostalgia. I am overflown with happiness and pride, and though I am just a speck in the universe of creators, I live for this passion (truly, creativity keeps me sane).

At CMD, every piece of jewelry tells a story. For our long-time client Becky, that story began with an engagement ring with a broken diamond setting and a collection of loose diamonds from her original wedding stack. She came to us with a vision of a mixed-shape stack [...]

I had no roadmap, no investors, and no idea where this path would take me. What I did have was grit, curiosity, and an unstoppable urge to create. Two decades later, CMD has grown into a small-but-mighty brand with a team I love, a community I treasure, and designs that still light me up at the bench. [...]

When it comes to jewelry, there’s something about a piece that pulls on the old heart strings — one that carries meaning, a memory, and a story only you could tell. Over the years, I’ve created countless custom designs. It never gets old to see a simple letter or name transform [...]

The day before Thanksgiving has always felt a little sacred to me. There’s a collective exhale in the air — a quiet pause before the food, the laughter, the inevitable second (or third!) slice of pie. Before we all scatter into our respective [...]

I never intended for my pinky ring stack to become such a conversation starter — but here we are! Over the last few months, I’ve received more comments about this stack than anything else I’ve worn in a while. Honestly? I get it. It's one of my newest obsessions, so let me tell you the real story behind it [...]

Our newest collection, BLACK & WHITE started as an experiment: How would it look to contrast the sparkle of our lab-grown diamonds against the crisp black of oxidized silver? The diamonds and oxidized components of [...]

This is a very special week, as my beloved grandma turns 100 years old on July 29! Does she look incredible or what!? I feel so grateful that my life has been surrounded by strong, inspiring women, and my grandma is a huge part of that unshakeable foundation.

If you haven’t been into the Showroom, I’d love to invite you to swing by and join me here. It’s my home away from home. You can check out our creative space (brimming with tools and sketches) and try on any of our beautifully finished pieces. We even have a Ring Bar where you can build customized stacks. 

CMD runs on woman power, and we’re all the stronger for it. We were delighted to spend the last few days at our New York Production Studio, all the way across the country from our San Francisco HQ. While we may span time zones, our common passions, worth ethics and respect for one another keep us closely tied together.
