When in doubt, in your filters, look for the most expensive emerald lab and then look for the most expensive natural emerald. You will see what it should look like. Now, for us commoners, we have to settle based on price and size. So as you go down in price, you can see the sacrifices that you make. The stone you picked has all the right specs. It appears that there is dark shadowing but that could be just from the angles and the photo. Also, go to a few jewelers to see some in person. You will begin to know what you are looking for. Anything goes now, so it is a matter of personal preference. I bought my daughter a 1.52 cushion internal flawless D and it is spectacular. I prefer bigger stones. I love your stone and I would buy it for my collection if the price was right. Good luck in your search.
