NGC COMMENTS
One of the largest color change spinels on the market. The blue is similar to a light blue sapphire and the purple is similar to an amethyst. This stone is ultra-rare. The majority of the value of any color change stone is the color change. According to AGL, color change is strong and the quality of the change is excellent. No need to use your imagination with this stone, the color change is obvious. Further, the color tone is 3/75. This means the stone is top color and perfect tone. The colors are vivid and the stone never "black-out." The clarity is MI1, so you can see some inclusions in the rock. The proportions and finish are extremely high at Excellent to Very Good. You rarely see these numbers from a stone from Asia. The depth is 78% and the brilliancy is 100%, or the same as a round diamond! Finally, the stone has the coveted excellent TQIR. Lastly, the stone has no clarity treatment or enhancement. The gem has also been graded by GRS. It contains the special comment, "A spinel of excellent clarity and brilliancy, with this color of low tone and pastel to medium saturation, combined with play of color due to dispersion is very rare. The play of color is achieved by a combination of an excellent cutting style and well-balanced proportions." See this comment in the link below. A 25.79 color change spinel recently sold for almost $9000 per carat at auction in Hong Kong, December, 2015. A fascinating gemstone to collect or a different stone to mount in jewelry.
