Colour and Clarity: According to Gübelin and AGL reports, the two sapphires are natural, of Burmese origin, with no indications of heating and clarity treatment. Please refer to the reports for details. In our opinion, the round sapphire is of medium deep, strong blue colour, and the pear-shaped sapphire is of medium deep, saturated strong blue colour, both are eye clean. Upon 10x loupe, both sapphires are very clean, only a few minor natural inclusions on side, not noticeable even under loupe check. Diamonds are about K to M colours, mostly VS clarity and a few stones may be SI1. Signed to the back. Condition: Vintage necklace, with signs of wear to the metal, overall in good condition.
