I think Crystal Gem Pearl is a Natural Variant of Pearl, whereas Blue Diamonds Pearl is a Cultivated Pearl. This can explain how CG Pearl is battle capable because Gemology speaking a Natural Pearl is made out of multiple layers of Nacre (an organic-inorganic composite material, and is strong and resilient - Wikipedia) Whereas Cultivated Pearls only have a coat of this surround a nucleus. This can then explain why Pearls Gem is Oval, and Blue Pearls is circular cause she's made. This can also explain why Peridot called her a "fancy one" not because of her clothes but because Natural Pearls are incredibly rare.
