A while back I purchased some Noondorite cabs from a dealer at a
rock show. He thought it was Adventurine in some kind of matrix,
but he was a broker not a rockhound. The only other info he
seemed to know was it is from China. The price was right down
with Black Onyx cabs, so I bought a handfull. Does anyone here
have any info on this stone?

A web search only turned up a retail source with no info on the stone.

Any info an composition and/or lore would be appreciated
