Hi Ray,
I don't know for sure, but I think it could be a John Deacons' piece. It looks like it started out as a "Flower In The Rain" weight, which is certainly seen with mottled pink ground, three green leaves and five coloured petals. However, in this case, the petals seem to have turned out very translucent and therefore not right for finishing as the regular paperweight (which would have had an outer covering of air bubbles).
Rather than waste the work, it has been flattened out and finished off as a shallow bowl. At least, that's my theory.
