Thx all for reply. The flourescent is nil. And it's indeed an HRD certificate. We went to one of Antwerps most brilliant jewellerstores. We live in the Netherlands wich isn't far away from Antwerp, Belgium. I tought that a VG cut was also a high cutting because only excellent is above and i didn't now about the HCA scope so now i've noticed it I'm in doubt. I tought it was a good deal/ diamond because it looked bigger more like a 1.2ct. In the store all the diamonds sparkled a lot so i don't think i could tell the difference anymore. But it was me that said that it was a nice stone, only one small pinpoint on the side.. In my mind (wich ofcourse could be terrible wrong) a diamond should always sparkle even when there's no (sun) light on the ring. But since I now have it, it doesn't sparkle all the time. My boyfriend bought it in january for approx. €8000 incl. A 18k white gold ring with 0.1c tw on sidesstones with D/E color and VVS clarity. I don't now if we can return / change it, altough the jeweller said that we always can get an upgrade with the same value.
I'm gonna check above link. I knew that cut was the most important factor but I really tought that a VG cut was also a high cutting grade. 🙈 I didn't do my homework properly I think.
