Montblanc Princess Grace de Monaco

A discontinued women's collection, pre-owned only. Launched in 2011 to honor Princess Grace of Monaco, in partnership with the foundation bearing her name, this was a jewelry-leaning ladies' line (spanning watches, writing instruments, and jewelry) with quartz movements, mother-of-pearl, and diamond settings. It's since been discontinued. A niche, elegant piece for a collector drawn to its namesake and era.
