An all time favorite allround beautiful dish with copious uses. These dishes are made of pressed glass with a very intriguing surface structure that ar reminiscent of roots or some kind of underwater creature. The dish is carried by a hollow base stem. They were made by Stölzle Oberglas in Austria in the 60s and 70s. They can be used to serve food, hold jewellery, candles, candy, whatever you want to showcase. 
There are 3 sizes available as can be seen in the last picture. 
 
Just like all vintage pieces small signs of use are possible.
