This large natural Penn pearl was found off the gulf coast of Mexico and weighs a whopping 21.9 carats.
Penn pearls are completely the byproduct of the mollusk fishing industry. They come from a shell called the Pinna rugosa or the Atrina maura. Only 30% of what is found are nacreous.
If you’re looking for something unique and one-of-a-kind, then this pearl is for you.
