This one-of-a-kind Sky Island inlay signet captures Mount Tamalpais with topographical accuracy. The sterling silver miniature charm maps the mountain’s ridgelines and contours, set into a piece of dendritic agate whose branching inclusions evoke the redwood forests that grace Tam’s slopes. Handcrafted with careful inlay work, the signet pairs geological detail with organic texture, that honors Northern California’s lush terrain. This ring cannot be resized.
