Diamond Quartz Ring size 9. This is a large Millennium cut diamond Quartz, Brazil, stone measuring 20x15mm and weighing in at 17 carat. The Millennium cut is one of my fave cuts because the sparkle is just fantastic. Due to the cut and the clarity of the stone this stone will take on the hue of what ever colour it is close to. If you are wearing red it is not unusual for the stone to have a pinkish hue. In the photo the stone appears to have some blue/grey hue….that was my shirt colour…..the stone is totally clear and eye clean. …It is just stunning.
