Need help identifying a sterling necklaces beads

I purchased this from a pawn shop and would like to know if anyone can give me any history or information on these beads. The necklace says the box chain was made in Italy but I can’t find hallmark on the beads which are approximately 8mm. They are slotted on the top. Thanks
