A simply lovely Estate ring set in solid Platinum and featuring a beautiful completely unheated and untreated Star Sapphire probably from Sri Lanka weighing an immense 4.58ct. The beautifully made Estate ring contains an array of clean and white round and baguette diamonds of excellent quality totalling 0.41ct. The unheated Star Sapphire is of a superb light grey blue, with grey the dominant colour, changing from a greyblue under sunlight or incandescent lighting (as per our first pics) to a greyish pastel blue with no additional lighting shone on the ring. You can see from the first pics, the stone exhibits a lovely star effect when put under a torchlight - the other pics have been taken under normal lighting conditions. Exceptionally rare and utterly unique! The ring can be supplied with certification from the AGL laboratory in Bangkok confirming no heat. We will seriously consider all close offers, but unrealistic ones will be automatically rejected. 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.
