Our Commitment: Handmade + Unique Jewelry

Kate Maller Jewelry features collections of fine rings, necklaces, bracelets, and earrings that celebrate the imperfections found in nature. The organic forms and rich textures of our natural surroundings inspire handmade + unique jewelry that elevates your sense of style, speaks to your desire for authenticity, and captures your heart.

Every piece of Kate Maller Jewelry is handmade in our studio in Denver, Colorado. We use only recycled high-quality precious metals, and reclaimed or ethically-sourced diamonds and gemstones. We’re deeply committed to the preservation of natural resources, and adhere to the highest standards for sustainability in jewelry making.

Kate designs and creates at least two unique + sustainable fine jewelry collections every year. Diamonds feature prominently in the collections. Diamonds are the hardest stone in the world and because they never erode, diamonds make an ideal heirloom—and their beauty is extraordinary.

Kate Maller Jewelry features fine jewelry for men as well as women. The first KMJ men’s line debuted in the Slice Collection for Men and Women in 2019. In 2020, Kate designed and introduced the first-ever KMJ contemporary bridal line, called The Legacy Collection. The line features an assortment of stunning engagement rings, wedding bands, and stackers as well as delicate necklaces and bangles. Kate also designs and makes handcrafted custom jewelry, and often incorporates repurposed gemstones and diamonds.

Client Reviews

Don't just take our word for it -

Briana Scibilia

Rachael Ray Show, New York, NY

One word I can say about Kate’s pieces – OBSESSED! I work with Rachael Ray on her television show and am always looking for fun new jewels to put on her. Every once and while I will find a designer that makes such cool, beautiful and unique pieces; Kate is definitely one of those designers! She is my go to whenever we need a great piece to put on Rach for a show and she always looks oh so fabulous in anything we put on her from KMJ. I mean, have you seen her cuffs?! Total heart eyes.

Dawn Paschal

Fort Collins, CO

I discovered Kate's beautiful pieces by chance in a Colorado jewelry store. They caught my eye immediately because of the way she combines oxidized silver with gold dust to create handcrafted items of unique and interesting design. The added bonus is her commitment to sustainable and ethical business practices. I currently own several of Kate's rings and bracelets and look forward to purchasing more from her collections.

Kelly Hall

Denver, CO

Kate worked with my husband to update and upgrade my wedding bands while expertly including stones from some heirloom jewelry into two custom rings. I never really received any comments, let alone compliments on my rings but now I have strangers asking me about these unique and beautiful pieces. They are a reflection of me, my marriage, and how we have evolved together over the last decade. I can't wait to add to my Kate Maller collection in the future!

Lyn Z.

Kansas City, MO

I met Kate at a local art show.  She worked with me to create custom pieces that are perfect!  I can’t say enough good things about Kate, the work, the process, etc.  Pick something out, you won’t be sorry!

Martie Pollard

Gales Ferry, CT

I love most how absolutely wearable the pieces are - even though a piece might look heavy I find it surprisingly light...the inside of the rings are also incredibly soft on the skin. My KMJ pieces are definitely my favorites in my jewelry collection.

Donna Leonard

Chicago, IL

I simply love Kate’s designs and workmanship! Her pieces are beautiful!
