Hi Alyce,

Thank you for contacting Mearto with your appraisal inquiry.
Chihuly chandeliers can command five and six figures at auction but there are also a lot of fakes on the market so my value is provisional based on the assumption that this is authentic. If you'd like to inquire about Mearto's authentication services, please let me know (if this were deemed to be a reproduction, or in the style of Chihuly, the value would be closer to $3,000-5,000).
Based on the photos and information provided, and subject to examination, this is:

Attributed to Dale Chihuly (American, b 1941)
Multicolored blown glass "Persian and Horn" chandelier
featuring Chihuly's distinctive Persian and horn forms, as well as squiggles and
48 inches tall
CONDITION: appears to be in generally good condition
PROVENANCE: acquired from a gallery/dealer
$40,000-60,000*
*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, and thank you again for using Mearto.
