I know one of the divers that worked for Mel. He said many emeralds were scattered during the sand removal operations where they used the ships props and a large curved “pipe” to blast the bottom clear of the sand prior to air lift vacuuming the site. It seems emeralds and sand have near the same specific gravity and all flew away together. They found many emeralds but just as many are still scattered all around there.

Yes. My understanding is that there still remains a good bit of treasure around the Atocha site.
