Nuked = bead-nucleated, that is, a bead is placed inside the mollusk along with a piece of donor mantle tissue that stimulates the formation of the pearl sac.
It's only in recent years that some freshwater pearls have started being nucleated with beads. Edison pearls, ripple pearls, fireball/flameball pearls all are bead-nucleated. These tend to be quite large compared to the solid-nacre FW pearls that have been around longer.
Not very many eBay sellers were mentioned, at least, I haven't been able to find them?
I guess I will chalk up the 3 pearl purchase and take it as lesson learned and make it practice pearls for drilling/jewelry crafting. They might still be beautiful, who knows! I will only find out when I get my hands on them .
Thank you everyone for your wonderful and kind help, the time taken to respond to my question is very much appreciated!
is a Flame ball pearl the same as a Fireball?
