My green glass something, I call it a serving tree

I've had it for years and have always been looking for a replacement bowl because one was missing when I got. It has six arms that hold little bowls and one large one on top. It's fifteen inches tall. I don't believe it's depression glass because it is so much darker than other green depression glass. I love it I think it's beautiful . It has no markings so I have been unable to identify it and buy more pieces. Any help or guesses would be appreciated.
