This is a vintage Murano art glass bowl or candy dish, sometimes described as having a starfish or webbed shape. 
Handmade in Italy, hand-blown art glass. 
The colors typically include clear, tan, brown, black, and amber shades with a tortoise shell effect in the center. 
The shape is abstract with a unique, organic look due to its hand-pulled arms. 
It is categorized as vintage original, often in a mid-century modern style.
