chunky blue bead necklace

Here is another necklace I have had for a while too, beads feel heavy like resin or clay. Does anybody know where or who made them ?

 Thank You

Looks like greek pottery pearls. Resin is not that heavy. When they feel quite cold and are
really heavy it's pottery. But there a tons of it. Impossible to identify such costume jewellery.
