Can a beholder’s disintegration ray destroy a non-magical item?

@MeimingNanashiCan a beholder’s disintegration ray target/destroy an attended non-magical item? If so, would there be a save? yes – I'd simply roll damage, no save

@MeimingNanashiI’m guessing the DM would then assign an amount HP to the object in question? yes
