Catalogue Note

"The described sapphire exhibits an impressive size and weight of 45.740 ct, combined with an exceptional purity and attractive well saturated blue colour. 

The few inclusions found by microscopic examination are consistent with those found in sapphires from the classic mines along the Mogok Gemstone Tract in Burma (Myanmar). Its attractive and saturated blue colour, poetically also referred to as 'royal blue', is due to a combination of well-balanced trace elements in the gemstone, which are typical and characteristic for fine sapphires from Mogok, Burma".
