[5] The global chairman of Sotheby's International Jewellery Division, David Bennett, when interviewed on the ruby, stated "during his 40 years in the industry, he has never before seen a ruby of this calibre". [5] In a Gubelin grading report, it notes, "ruby is of Burmese origin" and that "its vivid but saturated color, 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." [8] Gemstones of the same quality typically form in only small crystals, making this one an "extremely rare" gem. [8] History [ edit ]
