I bought this at an estate sale a while back, and am just curious to know more about it. I was told it's made out of black jade. It does change color in the light if viewed at a certain angle; changes to almost a golden color. It's very cool!

This is a hand crafted piece of artware from Red Wing (Red Wing pottery in MN). It is about 12"x 7" x 4" high. It is  glazed with a salmon color with grey  speckels. The bottom is stamped with " RED WING USA M-1463".  The edged are uneven and curled in and on outword curl. The former owner was in her 90's when she died, it was on a shelf in the basement. There are no defects that I can find. I can't seem to get the picture to download..sorry.

Found in the house we moved into about 23 years ago.  It's part of a coffee/tea set.
