Those are unusual colors for sea pearls, so maybe they are freshwater pearls? Very unsure what you have, so let's wait for someone else.
At first, I thought I detected a bead in the little fireball and maybe the one at the top right in one of the photos, but the backs are flat.
Also image shack photos always go away from the threads they get into, so would you mind putting the photos in the thread? These are interesting and unique and we would love to have a permanent record of them, here.
