KMJ All Jewelry

Artisan, Fine + Handmade Jewelry

From the sheen on an aspen leaf to the dramatic canyons in Costa Rica, the jewelry collections by Denver jewelry store owner and designer, Kate Maller, are inspired by the shapes, forms, and textures found in nature. In her travels to faraway places, or just hanging out with her dogs in the park, Kate is drawn to simplicity and power. Organic forms, surfaces, and structures, and the interplay of light and shadow influence her designs, first in her sketchbook and then at the jewelry bench in her Denver studio.

The pieces in every KMJ collection are designed by Kate herself. Once a collection has been designed, every piece is handcrafted in Kate’s studio and never out-sourced. Her knowledge of jewelry making and her skilled craftsmanship uphold the KMJ brand of excellence. Of all the aspects involved in creating original jewelry, landing on a theme for a new collection and designing the individual pieces is Kate’s passion. Her knowledge of architecture and landscape inform her work and she always goes beyond just beauty to include sustainability, which is the ground zero of Kate’s handcrafted jewelry. 

Every KMJ collection of rings, bracelets, necklaces, and earrings features recycled, high-quality precious stones and reclaimed or ethically-sourced diamonds and gemstones. Because there are no shortcuts in her process and no compromising of materials, the purchaser of a KMJ piece can be confident of the jewelry’s heirloom quality and lasting beauty. The unique, handcrafted artisan jewelry you love will be just as lovely when the time comes to gift your daughter on a special birthday, her college graduation, or her wedding day. The pieces are timeless, and handmade with care in our Denver, CO design studio.
