Pearl or not Pearl

[HARRY POTTER]

I hope that someone can help me to identify my Pearl..
Hope.
Thanks for any information that I can get

 

[Pearl Dreams]

Not a pearl.

 

[Lagoon Island Pearls]

Quartzite, not a pearl.

 

[CortezPearls]

Between a rock and a hard place!
What made you believe this could be a pearl at all?

 

[A Breaker]

I wonder if it is a fossilized egg?

 

[Cuon]

I wonder if it is a fossilized egg?

Almost certainly not. Fossilized eggs look quite different.

 

[BWeaves]

It's a rock.
