Art Deco style platinum navette ring, the oval sapphire of 1.45 ct flanked by triangular cut sapphires within a diamond surround.
A large oval sapphire lies across the centre of a pointed navette plaque, and a triangular cut sapphire sits at each side with its point running out to the tip, so the blue carries the full length of the design in three stones rather than many. Diamonds ring the centre stone and fill the shoulders. The centre sapphire at 1.45 ct is among the larger stones in the group.
