Hmmm very nice but I wouldn't label that as an Emerald. It's some stone in the rough but without a true Gemologist viewing, you would be wise just to state the color ie: Emerald color.
Top quality Emeralds can wholesale for over 10k.
Colombia Emeralds are considered one of the most beautiful. Emeralds are really just a Beryl stone, it's the impurities that create the color. Even the trace of iron in a Beryl can turn that stone into an aquamarine.
So with all that said, to be on the safe side if selling, just reference the color. Best to you, Silver
