Thank you all so, so much for being so generous with your time and advice! I feel much better making jewelry purchases thanks to this community!
Last two questions:
1. Should I be concerned about the small chip/surface inclusion on the right? It’s visible here
2. I’m dropping it off at AGL tomorrow to find out treatment. Is a Prestige ID report sufficient ($160) or should I pay extra for the Prestige Origin Report ($390) to make sure it’s Colombian? It’s not an investment grade emerald, and I’m not planning on selling, but I guess you never know, and I’m fine with paying extra if it’s the smart thing to do.
I would probably stay with the 4.04 even though it is a tad lighter than my usual preference. Although the new one has better colour, the middle just looks either cloudy or dead.
