On the subject of a new name for “Tiffany Stone” and after some
off-list correspondence with Tom Munson (who really knows this
material), I’m voting for calling it “Spor-opalite”: “Spor” for its
origin (Spor Mountain) and “opalite” because it’s less than pure
opal, has no fire, but has common opal as an essential ingredient.
P.S. Tom really does have some gorgeous stones for sale on ebay.
At the moment there’s only one example of Spor-opalite but the others
are well worth seeing. Go to ebay and search under “Sellers” for
