Need help with diamond purchase!

[Yasemin Lipscomb]

Considering this diamond from James Allen. The crown and pavilion angles seem to be outside of ideal parameters but I've requested an IS image which I will post when I receive (since I wont know what I'm really looking at!) https://www.jamesallen.com/loose-di...h-color-si1-clarity-excellent-cut-sku-4252101
Any feedback would be greatly appreciated!!!
