Colour and Clarity: According to GIA report, the cabochon sapphire is natural, of Ceylon origin, with no indications of heating. Please refer to the report for details. In our opinion, the cabochon sapphire is of medium blue colour, moderately included to naked eyes. Upon 10x loupe, there are crystals and fingerprint inclusions, with surface pits and abrasions, but generally not noticeable in normal visual distance. Diamonds together weighing approximately 0.40 carat, are tinted colour and SI clarity. Condition: Vintage ring mount, with signs of wear to the metal, overall in good condition.
