The 2.71ct Navette Tanzanite Ring

The mixed-cut faceting ensures the pleochroic colours—the natural shifts between blue and deep violet—remain sharp across the entire elongated surface.

​The History

​Whilst the silhouette of this cut has 18th-century roots, the stone itself has a much more modern history. Tanzanite remained hidden until 1967, when it was discovered in the Merelani Hills of Tanzania. It was famously championed by Tiffany & Co., who recognised that its singular, rich violet-blue could rival the finest sapphires.

Because it is found in only one place on Earth—a tiny four-kilometre strip of land—geologists estimate the chances of finding another deposit elsewhere are less than one in a million.

​This piece pairs that "one-generation" gemstone with a cut traditionally known as the 'Navette' (French for "little ship"). 18th and 19th-century jewellers favoured this name because the elegant, tapering points mirrored the classic lines of a ship's hull. It is a shape designed to visually elongate the finger whilst maintaining a strong historical silhouette.

​I have a marquise tanzanite myself and absolutely adore it—this combination is going to make someone very happy 😊
