I just peeked at your albums, David, in the unknowns, you have a pink thing with bubbles and inclusions (564 Chinese) which we believe is Romanian - does it have a bright sort of rainbowy lustre on the outside?
And the 582 thing, blue and green insidey bits, bears some resemblance to bits by John Orwar Lake I've seen, though somebody who knows his work better than I do should really be consulted before any attribution is made.
