Also, your stone is very nice and definitely has a top cut so if you are happy paying a premium for the "Astor" brand and the VVS1 clarity then go for it but at your budget you could probably get a higher colour with no flourescence without sacrificing much on the cut.

I dropped the Astor brand and found these: E VS1 https://www.bluenile.com/diamond-details/LD15356396?refTab=DIAMONDS&track=viewDiamondDetails&catalogView=true E VS2 https://www.bluenile.com/diamond-details/LD05901412?refTab=DIAMONDS&track=viewDiamondDetails&catalogView=true

I'm no expert, I probably have about the same knowledge as you so I would definitely get a second opinion on both of these stones but maybe someone on here like u/sproutworkshop can find you an even better deal. He helped me dodge a few bullets during my search.
