From the Chtelaine Collection. Chtelaine celebrates two distinct inspirations - David Yurmans mastery of sculpture and his wife, Sybils, sophisticated eye for color. The collection features chromatic gemstones, many of which are rendered in Davids signature faceted cushion cut and complemented by hand-set pav diamonds. As David says, every piece is designed to generate a deeply personal response.
