Measuring seven centimeters tall, this is a small glass bottle for perfumed oil. It was made by fusing ultramarine, green, and amber-colored transparent glass bands together, with gold leaf sandwiched in between the bands, creating "gold-band glass" with a marble-like design. This kind of advanced glass technique was developed from the end of the Hellenistic period to the Roman period. Very few complete pieces of gold-band glass exist today.
