Colour and Clarity: According to Gübelin report, the emeralds are natural, of Colombian origin, with indications of minor clarity enhancement. Please refer to the report for details. In our opinion, the emeralds are of matching, medium intense green colour, slightly included to naked eyes. Upon 10x loupe, there are natural inclusions with surface reaching fissures on crown and tiny nicks along table facets, but generally not noticeable to naked eyes. A few larger pear-shaped diamonds weighing approximately 1.00 or above each, are about L to M colours, SI clarity. Other diamonds are probably of similar colour to light yellow hue, SI clarity. Condition: Karat yellow gold mount, choker necklace style with signs of normal wear, otherwise in very good condition.
