Pearls are not formed in eggshells, rather they are created inside the shells of certain mollusks like oysters and mussels. When an irritant enters the shell, the mollusk secretes layers of nacre around it, eventually forming a pearl.
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.
Well I'm not sure but the only thing that I know about dinosaur eggs that they are big and not sure if bird or reptile eggs are big

If the pearls are described as faux, shell pearls, imitation, or anything other than cultured Freshwaters, then they are fake. More and more vendors are popping up selling shell pearls. Pearls that are described as "shell pearls" are not real. They are made from a compound of ground up shell and are faux pearls.

Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
