PANDORAMoments Sterling Silver Mother Owl and Baby Owl Charm 10.8 x 12 x 11.8mm (D/H/W), one size, Silver, No Gemstone

does it comes with a box?

is it sterling silver?

Does it come with an authenticity certificate, a pandora box? I ordered because of the stars this product has but it does no look authentic in reviews

Is this authentic?
