I love this gorgeous gem not familiar to most people. The trade name is "Titanite". Sphene has the second highest dispersion 'fire' of any stone, the highest being demantoid garnet. The third highest is diamond.
The beautiful color of a tropical ocean of this Kornerupine are probably related to the presence of chromium or vanadium. Because of the size, the color, and the clarity, this is the nicest Kornerupine we ever came across. This stone is step cut pear shape measures 9.70mm x 6.40mm x 4.82mm and weighs 2.01 carats.
