This is a rare jellyfish pendant, and it's the only one I've ever seen that features TWO opals, one down in the tentacles (which is more typical) and then one up in the body of the jelly, which I've never seen before. Maybe it's the mother jelly, with a bright shining brain?? It features three tentacles wrapping upwards, and three going down, so with the two opals, it's a triple double in a couple of different ways! You rarely see the tentacles going up like that, as it's more work to create the jelly that way - it's 'double-worked'.
