AN ANTIQUE EMERALD AND DIAMOND NECKLACE
The two rows of rectangular-cut emerald and old-cut diamond graduated clusters interspersed by diamond collets, to the similar single-row backchain, mounted in silver and gold, early-19th Century, shortest row 40.5 cm
Accompanied by report no. 61999 dated 6 February 2012 from the SSEF Swiss Gemmological Institute stating that the emeralds are of Colombian origin, with none to moderate amount of oil; and an Appendix indicating that 'The emeralds (...) exhibit a well-matching colour, combined with a fine purity. Microscopic examination revealed inclusions, which represent the hallmarks of Colombian emeralds from the famous mining areas such as Muzo, Coscuez, and Chivor, all located in the green foothills of the Cordillera Oriental in the Colombian Andes.'
