Andy,
here is what I see:
1. It’s a natural emerald – good
2. It’s IGI certified – good
3. Origin: Colombia – good
4. Size: Big but nothing extraordinary
5. It has significant clarity enhancement – not very good. Almost all emeralds are clarity enhanced by colorless oil, that’s perfectly ok. However, there are 3 enhancement levels: minor, medium, and significant. The more enhanced, the lower the price.
6. Color – bad to very bad. This emerald is rather light green, color is not saturated. This is significant because the most important thing is color when it comes to emeralds. In addition, color distribution is uneven.
7. Clarity – bad to very bad. It has really severe inclusions. Almost all emeralds have inclusions and other growth features (unlike diamonds), but this one is heavily included. Note that so many inclusions can also compromise how durable it is. This is why jewelers don’t love emeralds with too many inclusions – they can break into pieces while being placed in the setting. This can also cause problems if you accidentally drop your piece of jewelry.
8. Cut – bad to very bad. It is very deep and uneven. This not only makes it less attractive and less valuable but also makes it more difficult to work with (for a jeweler, I mean).
9. It has nicks and chips – bad
Conclusion: an emerald of inferior quality worth maximum $500. The price estimate is heavily inflated and has nothing to do with the stone’s quality and true market value.

Bergholm,

Before I say anything about the price, I’d like to say a few words about another important aspect here – the quality. I have bought and sold many diamonds (including pink diamonds), and I am very much familiar with this type of pink diamonds – I2 – I3 clarity diamonds (referred to also as Piqué). It is good that the description is honest on this. The seller clearly states that it is I2 to I3 clarity.
What is not entirely honest here, it’s the images. They are photoshopped and substantially enhanced. In reality these diamonds are by far not that vivid pink and saturated. They are much paler and with a brownish hue. I attach an image of a pink diamond here that I bought about a year ago. It’s stock photo was as vivid-pink as yours. So, the reality is very much different. It is always the case with these pink diamonds. So, don’t even dream that this case here is any different. I guarantee you, it is not.
Secondly, these diamonds always have some nicks and cracks. They are always hidden in the images in order to get a better price.
Last but not least, the price – $2490 for this diamond is absolutely outrageous. I have always been buying 1+ carat diamonds (I mean, the same quality and color as this one but bigger). The price range has been from $250 to $290 (including shipping). Oh, and that did include a certificate worth another $30. So, we come to a price of $220 to $260 for 1+ carat diamond. This one should cost no more than 1/2 of that then.
