Gold was once called the metal of the sun, silver the metal of the moon, and this gender-neutral ring joins the two. Its silver line curves inward, crossed by a slender pin of 18K white gold, so that long and short lines seem to intersect.
In 2016, a designer whose hobby was analyzing plant structures spent long stretches observing the stamen revealed between petals. She was struck by how the stamen, thin and seemingly fragile, was in fact the strong axis holding up the entire flower — and by the way it moved, swaying with flexibility even in the wind. This discovery, a reinterpretation of the flower's anatomy through a new lens, took shape that same year as the concave silhouette of the CONCAVE PIN RING.
Traits of Bone is COLDFRAME’s first collection, born in New York in the early summer of 2016. Inspired by the shape of the female pelvic bone and of the stamen deep inside a flower, its silhouette is thin yet sharp, strong yet fluid. It was completed over many long, happy nights of discussion with friends studying art in New York — an original and bold beginning for COLDFRAME.
