Color Analysis by Gemewizard
On November 29, 2011, a cushion-shaped Kashmir sapphire of 26.41 carats sold for $3,838,508 at Christie's Hong Kong. The $145,342 per carat price was highest ever recorded for a Kashmir sapphire.
To mark that event, we selected this time to focus on Kashmir sapphires, and for that purpose we selected a magnificent platinum ring, set with a 14.44-carat flawless blue Kashmir sapphire, accented by two trapezoid diamonds, each weighing 2.08 carats. This item is being offered for sale by MS Rau Antiques in New Orleans for $2,250,000.
We took the ring image and marked the gemstone borders. Then, we analyzed the area using the Sampler feature of GemeProTM. The Sampler gave us the color components of the image together with its Color DNA. Using a sophisticated algorithm, the Sampler identifies the sapphire color code as GW 23_6_6, also known as 'medium dark vivid violetish blue' by GIA® definition.
In order to get better perspective of the color, we placed it in the violetish blue color palette and discovered that this gem is located in the right hand side edge of the hue with very high saturation and medium dark tone. This combination, together with the violetish blue hue, gives the gemstone its deep and rich color.
