Minimal Arc CharmA 147mm 925 sterling silver arc charm clean geometry, no stone, no surface decoration. The Minimal Arc is the foundational charm: a shape that works as punctuation in a larger collection or as a solo pendant worn on a fine chain. At 0. 63g, barely there in weight but present in form. The high polish arc has a clean light reflection that reads as deliberate against any background. For those who build their charm collection from neutral shapes outward.
