Sculptural, thick, clear crystal dish that slopes up. The diameter of 5.25" and 5.75" at the attached piece -- originally for holding a cigarette. The height slopes from 2" to 1.25". 

This piece is in excellent condition. It has a few light scratches on the flat underneath part of the bowl. These are not visible when the dish is not bottom side up. 

A lovely minimalist piece by David Hills.
