With yellow and green being the primary colors in most parti sapphires, let us explore the phenomenon leading to the formation of these colors. Gemological science is intimately associated with the color theory, which makes sense as colored gemstones primarily hold their value based on their unique coloring.

This means that unlike dual-toned stones like teal sapphires, the two colors have a distinct band of separation that doesn’t allow the merging or blending of one color into the other. While many sapphires have the same color composition, parti sapphires are different because of the presence of distinct bands of color that is called color zoning. Green is created by the presence of both titanium and higher traces of iron than seen in the blue coloration. Iron imparts a yellow or yellowish-brown color whereas blue areas have a higher concentration of titanium and less iron. Parti sapphires contain impurities like iron and titanium that give them their characteristic color. Just like all sapphires, parti sapphires belong to the corundum family and therefore come with all the associated physical properties that make them so valuable. WHAT ARE PARTI SAPPHIRES: Composition ChartĪlso known as polychrome sapphires, parti sapphires are made of a natural blend between two colors, generally yellow and green.

It can be said without qualms that absolutely no two parti-sapphires are alike. While these inimitable stones have been around for a while, parti sapphires have only recently begun to grab the public eye due to their unique color.
