Accompanied by report no. CS 51336 A & B dated 6 september 2012 from the American Gemological Laboratories stating that based on available gemological information, it is the opinion of the laboratory that the emeralds weighing 13.20 and 12.18 carat are natural, the origin of this material would be classified as classic Colombia, clarity enhancement: faint; also accompanied by an appendix stating that the emeralds are singularly distinguished and together make a pair of unique rarity. both exhibit an intense and saturated green colour that is representative of top-quality stone from Colombia. emeralds of such colour and quality are commonly referred to as "old-mine" emeralds and are considered to have originated from the Muzo mining district in western flank of the Cordillera oriental. AGL has developed a match pair rating that defines the comparative similarity in appearance of two gemstones and reflects the uniformity of all quality parameters. these two emeralds described received a rating of excellent. the total combination of quality elements, origin determination, match rating, as well as important ear pendants, represents a particularly rare example of a very fine emerald and diamond jewellery

Two duplicate reports nos. 11182466 and 13104080 dated 17 july 2000 and 16 january 2004 from the Gemological Institute OF America stating that the 3.09 and 3.03 carat diamonds are fancy intense yellow, natural colour, internally flawless and vs2 clarity respectively
