IGI Certified Natural Blue Sapphire | 1.87 Carat Oval Mixed Cut | Luxury Gemstone

Product Description

A striking 1.87 carat natural blue sapphire, certified by the International Gemological Institute (IGI) International Gemological Institute, featuring a rich and captivating deep blue color.

This gemstone is cut in a classic oval mixed cut, designed to maximize brilliance while showcasing the stone’s vivid color and natural character. Its elegant proportions and highly desirable size make it an excellent choice for rings, pendants, and other fine jewelry creations.

The IGI report states that this sapphire has undergone high-temperature treatment with color diffusion from an external source. Diffusion treatment introduces coloring elements into the surface layers of the stone to enhance or create its blue color. This treatment is permanent but significantly affects market value compared to untreated or conventionally heated sapphires.

With its attractive appearance and internationally recognized certification, this sapphire offers strong visual appeal at a more accessible price point.
