Hi Gina,

Thank you for contacting Mearto with your appraisal inquiry.

The use of alternating solid bands of color with multicolored swirls is a feature seen in Midcentury modern art glass, both in Murano, Italy and in other glass-making centers.
Unattributed vases - ones without signatures, labels, stickers, etc - of this size and shape typically sell at auction for less than $300 but if you can find a signature (look on the bottom or along the edge of either the top or bottom rim) let me know as it might increase the value.

Based on the photos and information provided, and subject to examination, this is:

A vintage large Midcentury Modern cased art glass vase
unattributed maker, mid 20th Century
Of circular section and asymmetrical form, with cased interior, the exterior with bands of lemon yellow interspersed with multicolor swirls.
23 inches tall; 8-9 inches diameter
CONDITION: This vase appears to be in good condition; value assumes no breaks, repairs, or losses.
PROVENANCE: Found in a second-hand store
$150-250*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
