Colour and Clarity: According to AGL report, the sapphire is natural, of Kashmir origin, with no indications of heating and clarity enhancement. Please refer to the report for details.

There is only minor abrasions along facet edges and one tiny nicks on table corner, not noticeable even upon loupe check. Calibrè-cut emeralds are of brilliant intense green colour, eye clean. Diamonds are about E to F colours, VS clarity. Signed and numbered to the shank, with platinum mark. Condition: Signs of wear and fine scratches to the shank, otherwise in very good condition.
