That's a tough one Michael.
There are literally hundreds of tunnels in Coscuez but just a few are in activity today.
I have quite a few specimens from Coscuez but I gave up on trying to get specific information about the localities.
What comes to my mind at first glance is that this a very nicely balanced specimen. I also like the step-like termination which is probably found more in Coscuez than in any other mining district. Excellent photo too!
Am jealous now :-)

| Thank you Tobi and Gerard. It was your thread Gerard, showing so many beautiful emeralds that inspired me to look for a Colombian emerald for my collection.

Thanks Michael.
Beyond the satisfaction of sharing my passion for emeralds, this is the best reward I could possibly get from my thread.
