I am relatively new to the gem world so I had a rather novice question to ask. What would be the ballpark value and rarity of the specimen pictured below? They are all of Zambian origin if that is of any help. I have yet to get an accurate carat weight, but I have a penny in the photo for reference.
Any advice or input would be greatly appreciated!
