Designed as an elongated hexagonal-shaped emerald plaque weighing 133.26 carats, engraved to its contours, carved during the 17th Century in India, measuring approximately 59.30 x 36.85 x 6.40mm. Accompanied by a certificate from the SSEF stating that the emerald is of Colombian origin with minor amounts of oil in its fissures. Also accompanied by a letter from the SSEF detailing its exceptional nature: "The natural emerald described in Gemstone Report No. ** from the Swiss Gemmological Institute SSEF possesses exceptional characteristics and merits special mention and appreciation.
The described emerald exhibits an important size and weight of 133.257 ct, combined with a serrated and homogeneous green colour and and fine purity. It has been cut into an artistically engraved hexagon, reminiscent of the original shape of the large emerald crystal from which this gemstone had been cut.
The small inclusions found by microscopic examination and the analysed properties are consistent with those found in Colombian emeralds from the famous mining areas Muzo, Coscuez, and Chivor, all located in the green foothills of the Cordilera Oriental in the Colombian Andes. The attractive green colour of this emerald is due to a combination of well-balanced trace elements, which are typical and characterstic of the finest emeralds from Colombia.
There is a long-established tradition in the trade to fill small fissures in emeralds with colourless oil to enhance their clarity. An emerald of such a size containing only a minor amount of oil in fissures at the time of testing is rare.
A natural emerald from Colombia of this size and quality can be considered very rare and exceptional."
Purportedly from the collection of Maharaja Sawai Pratap Singh of Jaipur (1764 - 1803). A drawing by Sahib Ram in the Jaipur City Palace Museum shows Sawai Pratap Singh wearing this emerald set in a sarpesh. It was also purportedly worn as an armlet.
