Giant clam pearl?

[12wentworth]

I was looking at this pearl. What kind is it?

Sweet Lord!
Just the name of the pearl itself leaves little doubt: "Massive Natural Ocean Pearl from Giant Clam Pearl Ultra Rare Australian Opalized Giant Pearl"

Looks like a Chinese Freshwater pearl to me...a Fireball.
Definitively NOT: opalized (what the heck do they mean by this!), nor ultra-rare nor Australian.
Or they best should have a Certificate issued by a prestigious Gem Lab.

Thank you. Just what I thought, too.

That pearl definitely grew in a freshwater mussel, not a Giant Clam

The same seller has this ultra-rarity -

And of course -

Both are also freshwater pearls

I hesitate to check the rest of the listings.
