Honestly, there'd be no way of telling because a fight like this depends on the battlefield. Give Lapis enough water and she'll beat almost anyone. Sugilite could be over three times as big and not stand a chance against Lapis................... Unless there's no water nearby. If Lapis doesn't have water to fight with, she's screwed. She can fly around all she wants, Sugilite will eventually land a hit and then smash her to pieces.

So in short: this fight depends on where the battle takes place. Seeing how easy it was for Lapis to steal the ocean, Sugilite has no chance on Earth.
