Sharon Stone is one tough cookie … because she powered through a black eye on a European getaway.The “Basic Instinct” star just shared a photo showing what appears to be a massive shiner covering one of her eyes … which she apparently suffered on vacation in Turkey.

Sharon says … “This trip has been tough; but I’m tougher.”Unclear where, when or how Sharon suffered the apparent injury … but she doesn’t seem to be letting it ruin a good time.

In a subsequent post on her Instagram story, Sharon shared an image of the backyard in her hotel room … and there’s a private pool with a patio and stone wall.Yeah, she’s balling.
