In the case of the Teal Sapphire, their stunning blend of deep blue and green comes from the presence of both Iron Titanium (Fe + Ti). Teal sapphires show a gradient of shades, varying degrees of blue, green, yellow, and space grey. The most precious teal sapphires have an equal or near equal composition of blue and green primary colors with hints of yellow, which depend on the reflection of light within the gem as well as the cut. The rarest and most valuable grade of teal sapphire has a 50-50 blue and green composition. No two teal sapphires are alike. Like padparadschas, each teal sapphire seems to have a unique personality reflected in its color variations. Their ability to surprise us with their unique hues and tones makes them very special. Note : Many people mistakenly call these gems "parti-sapphires." Keep in mind that "parti" stands for partition, which means colors separated into distinct color zoning bands. This doesn't occur in teal sapphires.
