A simply magnificent Estate ring set in solid Platinum and featuring a stunning Blue Sapphire from Sri Lanka weighing an absolutely impressive 5.05ct. The beautifully made Estate ring contains an array of clean and white diamonds of excellent quality totalling 1.73ct, these diamonds are truly top top quality. The central Blue Sapphire is simply gorgeous - a deeply saturated slightly darker hue - often called 'Royal Blue' - which at its best, like this example, shows extreme fire and vibrancy, and is absolutely eye clean, with only some *very very very tiny* inclusions visible under a loupe. Such excellent clarity in such a large blue sapphire is absolutely rare and absolutely to be collected. Lustre and brilliancy are excellent - the stone is positively 'alive' and is exceptionally vibrant and lively. The diamonds are all white and super clean. The sapphire has been heated as per industry standard (simple heat only, no other treatment whatsoever). We will note consider even a very near offer, as this ring already represents exceptional value. Without a doubt one of the finest Royal Blue sapphire rings on the international market today, and certainly the best value. Size 6.25 approx. Needless to say the ring makes a stunning statement when worn and is absolutely certain to appreciate in value as time goes by.
