Antique Butter Dish I Have Granite Counter Tops And Would Like To Know If It's Safe To Leave My 2 Marble Cutting Boards On Top?

I have granite counter tops and would like to know if it's safe to leave my 2 marble cutting boards on top? - antique butter dish

I use the marble cutting boards occasionally, but I lay it on the counter to show some types of salt, butter dish antique marble vases with fresh damage herbs.Will contact with the surface of my counter? I can under clean once a week and let the surface dry before they dry on the counter, I'd been there all surfaces.
Thanks in advance ...
