Help with an emerald diamond

[tonymo2020]

I am going to be buying an engagement ring very soon and I had a question with a stone I found. It is a 1.23, F, VS1 for a price of 6600. It is a really nice looking stone and has a nice sparkle to it. My question and concern is that the depth is 51%. It is a little thin but sparkle very nice. It also looks like a 1.50ct stone. Can anyone give me any advice
