About This Stone

This 1.55 carat sapphire from Sakaraha, Madagascar shows a striking bi-color combination of deep blue and colorless areas that shift as the stone moves in the light. The custom geometric concave shield cut gives the gem a bold architectural appearance, with curved facets that create lively reflections across the surface. Madagascar sapphires are known for their unique color zoning, and this stone highlights that natural character beautifully. Its distinctive shape would lend itself well to a ring or other custom jewelry design where the unusual cut can take center stage.
