Not Hallmarked but tested as silver (the chain) and 9ct white gold the pendant
Central Blue zircon ; This is absolutely stunning, the stone is one of the best zircons that I have seen- a very deep vibrant colour and absolutely no surface wear. Total carat weight 8ct. Measures 13mm
Total diamond content; 0.10ct
Necklace drop; 37mm
Necklace length; 17 inches
Blue zircons now cost approx £400 per carat, so even for this stone the cost would be £3200
Superb condition, no signs of wear. This is an absolutely stunning original piece of jewellery.
