Some jewelry stores sell rings. Gunderson's Jewelers sells the moment wrapped around them — and Sioux Falls has understood that distinction for a long time.
They design custom pieces from scratch, set diamonds, restore heirlooms, and repair both jewelry and watches — covering the full arc from proposal to anniversary to "this was my grandmother's and I need it to last another generation." Their clientele ranges from first-time engagement ring buyers trying not to panic to collectors who know exactly what they want and need someone who can actually deliver it.
People keep coming back to Gunderson's because the work is specific, not templated. A custom design here means someone actually listened to what you described. Heirloom restoration means the piece comes back looking like itself, not like a generic approximation. That combination of craft and attention is harder to find than most people expect — until they do.
