Skilled artisans handcrafted high-art glasswares. Opalescent pieces have unique gradations and colors, making each one individual. Opalescent glass is beautiful, changing its appearance and shimmering depending on the light and angle. Frill diameter: 16 cm Height: 5.5 cm It is in beautiful condition with a nice luster overall, but please consider that it is an antique item that has been through many years. Thank you for your consideration.
