Heart shaped Aquamarine stone

Heart shaped Aquamarine stone. I took the stone to the jeweler last week. He informed me that the stone has several inclusions that are characteristic of aquamarine. However, there is a bit of challenge to differentiate it from a very blue topaz. Nonetheless, the stone is valuable if it is aquamarine or topaz. The stone was sold to me as aquamarine, I no longer have the certificate of authenticity, so this is why I have listed it at a much lower price than what I have purchased it for. Please feel free to make a better offer! I am happy to see this beautiful stone go to a good home.
