Very blue Aquamarine stone, heart shaped

This is a larger heart shaped aquamarine stone. This has been inspected by a local jeweler who has informed me that the stone is most likely to be aquamarine however, it shows characteristics that are similar to both aquamarine and topaz. Due to the number of inclusions he felt that the stone was likely aquamarine, however, it would need to undergo additional testing. The stone was originally sold to me as aquamarine however, I no longer have the certificate of authenticity. Hence the reason why I am selling it for a much lower price than what I have originally purchased it for. The stone is very beautiful and radiant. Is one of the most beautiful aquamarine I have seen! please feel free to make an offer as I would love to see someone enjoy the stone and have it set an a piece of jewelry.
