This is a very rare stunning blue and white zircon ring set into a rose gold cluster.
The ring is not hallmarked but tests as such
Blue zircon; 8mm with minimal rubbing to the stone. A lovely vibrant deep colour. Do not confuse with the more readily available cubic zirconias. These stones are now rare, and expensive to buy at £400 per carat new.
White zircons; 2.5mm.
Ring head diameter; 13m
