When I started CMD over twenty years ago, I never could have imagined how far a conceptual idea of stacking circular and square rings would take me. What began at a tiny San Francisco workbench has grown into a full-fledged jewelry studio — now based in Upstate New York — where my small but mighty team of women handcrafts every single piece you see on our website. From design to delivery, we do it all by hand, with heart.
Recently, something a little magical happened online. A longtime CMD fan named Tayci had built her own Dream Stack during a virtual appointment with me a few years back — eight rings of silver, gold, rose gold, and oxidized silver — layered perfectly into a square, gorgeously sculptural little tower. We listed her stack online so others could shop her creation, and we’ve since sold a handful over the years.
Just recently, I posted a TikTok of Tayci’s Dream Stack after a client purchased one online. That post ended up getting thousands of views, hundreds of likes, and more than a few “I need this stack!” comments.

It’s been so fun watching the excitement unfold, because this is what CMD is all about: interactive design. Jewelry that invites you to play, mix, and express yourself. Every stack tells a story — and no two are ever quite the same.
Your Dream Stack is more than just a group of rings — it’s a signature set of pieces that live on your hand and capture your personality and style just the way you want. It’s part armor, part art, and all you. Whether you’re drawn to thin and dainty or bold and architectural, you can combine different shapes, textures, and metals to create something that feels balanced, beautiful, and uniquely yours.
Some people start small with a Minimalist Stack — two or three slim bands in mixed metals. Others go full-on Statement Stack, layering thick silver densa rings, oxidized accents, and pops of gold… maybe even a little diamond bling. Most of us live somewhere in between, adding and swapping rings as our moods (and outfits) shift. I certainly have clients who have collected so many rings over the years that they have their own personal Ring Bars at home. I also love our rings mixed in with other designer’s work.
If you’re new to CMD, we offer a few ways to start your stacking journey:
If you’re unsure of your size, I recommend first getting our adjustable ring sizer to get your general size. If you are ready to purchase and would really like to try on physical rings, we offer an at-home ring sizing kit, which serves as a rental. Once returned, your deposit can be applied toward your purchase. We offer the sizing kit in round, square or mixed shapes and you can try on three sizes with each kit.
Every CMD piece is handmade to order by our very skilled production team (Ary & Sam) in our Upstate New York studio. We solder, shape, file, polish, and finish each ring with care. The oxidized finishes evolve over time, softening into a warm antique patina. We think of it as jewelry that lives with you — getting better, more personal, and more “you” with every wear. Grab an oxidation kit if you’d like to occasionally oxidize your rings at home - it’s a fun little DIY project!
If you’ve been following along with us on TikTok and find yourself thinking, “I want to build mine,” this is your sign. Book an appointment, shop pre-designed stacks, or stop by The CMD Shop this Saturday, November 1st and Sunday, November 2ndduring my open hours 11am to 4pm (both days) for some ring play. You might just create the next viral stack!

While I’m out here, I’ll also be opening a limited number of in-person designer appointments in San Francisco. These are perfect if you’ve been wanting to recycle diamonds, 14k gold, or sterling silver, or you’re interested in a custom or special-occasion piece! It’s also a great chance to meet if you can’t make it to one of the pop-ups but still want dedicated time together. [...]
The first Happy Hour Sale of the year officially begins today, and whether you’re a longtime collector or brand new to CMD, I wanted to take a moment to share what Happy Hour is all about, and why it’s become such a beloved tradition in our little corner of the jewelry world. The Happy Hour Sale has become a way for me to try new ideas, for you to [...]
CMD is on the road (again!) — and this time, I’m heading west for a good chunk of the winter. I’ll be living in San Francisco from January 31st through March 31st (pinch me!), with Migs and all the jewelry in tow. I already have a couple of February events on the calendar, with more in the works for March. There's nothing quite like seeing you in real life, stacking in real time, and helping you find your next piece of everyday armor [...]
