A large deeply cut circular facet provides a flat surface on which the hemispherical cup securely rests. Above is a row of fifteen circular facets, then a row of another fifteen circular facets, and then a third row of fifteen facets, and the a fourth row of seven facets, the bottom is rounded and slightly indented inward.. A brownish weathering iridescent crust covers some of the surface, but it has peeled away in parts revealing the color of the glass and some iridescence.
These facet -cut bowls typically have thick walls. They were highly prized in antiquity, traveling as far as China, Korea, and Japan. Scholars hypothesize that some of them probably arrived with Sassanian princes fleeing eastward from Arab invaders in the 6th-7th centuries AD, while others were taken east by Persian merchants traveling across Asia.
