Bluish colorless glass, with dark brown and yellow luster stains. Blown, tooled and lustered. The cup has wide flaring sides, a small rounded base (does not stand upright), and a rim thickened by tooling. Horizontal bands of geometric, calligraphic and vegetal decoration were applied in luster stains around both the interior and the exterior. Approximately half of the decoration was applied on the interior, the other half, sometimes overlapping, on the exterior. A six-sided star decorates the bottom interior. Very few scattered small bubbles in the glass; pontil mark on base.
