Property of a Lady of Title
Important sapphire and diamond necklace
The front of scroll design set with brilliant-cut, baguette and tapered baguette diamonds, supporting a detachable pendant set with a pear-shaped sapphire weighing 37.50 carats within a border of brilliant-cut diamonds enhanced with baguette diamonds, length approximately 410mm.
Accompanied by SSEF report no. 131874, stating that the sapphire is of Burmese origin, with no indications of heating; together with a special letter stating an approximate age of 30 million years.
'The analysis of the zircon inclusions within this sapphire reveal an approximate age of 30 million years. This calculated age is well in agreement with the age of sapphire formation in the Mogok Stone Tract in Burma (Myanmar) as part of the Himalayan orogeny and as such this age further supports our opinion on the origin of this sapphire.'
