Our very own in house jewellery expert Tatiana Sieff comments on Kate Middeleton’s necklace:

Tatiana comments: “The sapphires in Kate’s new necklace definitely mirror the stones worn by Diana in terms of their shape, tone & saturation.

The quality is second to none – the sapphire boasts an even colour throughout, is beautifully cut and totally eye-clean and the surrounding diamonds have been hand-picked to perfectly match one another.

“It appears as though a bail and chain have been added to revamp one of the sapphires from the original Saudi Suite’s earrings so it can be worn around her neck, including the original diamond halo being kept to maintain its heritage.”

With the centre sapphire weighing approximately 3.00-5.00ct, and the original halo totalling a further 6.00ctw, I would easily estimate this piece to be worth between £20,000-25,000, perhaps even more given the provenance of this piece.”
