This Art Deco solitaire engagement ring features a 1.23 carat oval cut blue sapphire set in a four-prong basket on an 18 karat white gold band. The oval cut maximizes the sapphire's size appearance while producing good light return and color saturation throughout the stone.

The deep blue color is what makes sapphires highly desirable, and this stone shows strong, rich saturation. The mounting features intricate filigree metalwork throughout, characteristic of 1920s-1930s design. The white gold provides a cool-toned backdrop that enhances the blue color of the sapphire.
