Handkerchief Vase Clear 10" Ruffled Edges Polished Base-Is It Glass or Acrylic?

This is a clear vase in a handkerchief style. It may be glass because it rings when it is tapped. Google say that acrylic or plastic will not ring, it makes a dull thudding sound. I just can't tell for sure. It is very pretty, either way so I'm just selling it as a handkerchief vase, material unknown. Additional Google Lens details include: • It is approximately 10 inches tall, with a 3 inch base and 9 inches across the top. • The style is considered contemporary and may complement various interior designs. • It could be used as a decorative piece or for holding flowers. • Similar vases are sometimes attributed to designers like Jane Seymour. • Handkerchief vases are also associated with Murano glass artistry. In good condition with small imperfections consistent with age and use. I pack all fragile items in double or heavy duty boxes and use lots of bubble wrap. This sometimes increases shipping fees but I want your item to arrive safely.
