From Sotheby's:
"The described ruby exhibits a very impressive size and weight of 25.596 ct, combined with a highly attractive colour and a fine purity. Its colour is further pronounced by its well-proportioned cutting style, resulting in vivid red hues due to multiple internal reflections. Due to complex geological formation processes rubies of such quality generally are found in small crystals and only very exceptionally in such a size as the present stone. [...]Its vivid but saturated colour, poetically referred to as pigeon blood red, is due to a combination of well-balanced trace elements in the stone, typical and characteristic for the finest rubies of Mogok. [...]Based on our records we can conclude that a natural ruby from Burma of this size and colour is extremely rare. Thus, the described gemstone with its combination of outstanding characteristics can be considered a unique treasure of nature."
