Greetings,
I have a certified 5.37ct oval cut dark green emerald from Zambia, heavily included, translucent, fissure/chip on one of the back facets as pictured.
Any real world experience with piece valuation? I.e. Likely private market value? (IGS Valuation tool and ChatGPT is suggesting far higher price than I believe it would fetch).
IGS ($35,442)
ChatGPT ($18,795, though when I specify chip/surface inclusion it estimates $2,685 - $8055)
Pictures for reference.
Input would be much appreciated
