13.50 CT Quality Natural Blue Sapphire

A loose natural blue sapphire of 13.50 carats, fancy cut and blue, but the listing says it has been treated with beryllium diffusion. That treatment lowers value for most buyers, so this suits gem dealers who sell treated stones at a discount or who re-cut them. Get the treatment disclosure in writing before bidding, and check the photos for color uniformity.
