Princess pattern Anchor Hocking depression glass cake stand in green, so pretty. I think this probably glows under a black light, I didn't have my black light handy, and didn't test it.
Replacements dot com calls this a cake stand, but I'd call it a plateau - the top is flat, and it has little feet on the bottom. This measures about 11 1/4" across the handles, 8 1/2" across the center.
It's about 80 years old, and has been used and loved over the years. There's a little scratching or utensil marks to the surface, and a few small chips to the rim. Not a mint condition piece for a collector, but a good piece to use and enjoy.
