Unique Engagement Rings

Engagement Rings in Boulder, Denver, & Greater Colorado

You’re looking at a small representation of the thousands of unique engagement rings we’ve designed and made over the past 35 years for the surrounding Denver community – and beyond. The art and craft of unique engagement rings is our passion, and we take great pride in blending state of the art technology and old world craftsmanship to create hand crafted pieces that are truly one-of-a-kind.

As you browse through our portfolio, keep in mind these are actual photos of actual pieces, not digital renderings, that we have crafted from initial concept to final polish. We work in yellow gold, white gold, platinum, and palladium and make all of our custom jewelry in-house from start to finish.

Let your imagination and your individual story guide your design to result in a piece of art that is as enduring as it is beautiful.
Let Cronin Jewelers be the Jeweler that makes your custom unique engagement rings!
