This is unique handmade geode pottery trinket dish.  The top is green and underneath there is some blue.  I do not recognize the backstamp so I am unsure where or who made this piece.  The dish is a nice weight, is 4.5" in diameter and there are no issues to note.  This is perfect to display or use for small trinkets!  Thanks for looking and be sure to check out my shop, not2shabbyshop, for more fabulous finds!
