  Valuation Breakdown

  Because this piece is likely an unsigned production item or a high-quality "Murano-style" import, its value is based primarily on aesthetic appeal and size rather than brand provenance:

  • Unsigned/Vintage Marketplace Value: Similar 3.5-inch to 4-inch blue swirl egg paperweights consistently fetch $12.99 to $14.99 on secondary platforms like eBay. 

  • Vintage Boutique Value: Curated online vintage shops on platforms like Etsy sometimes list comparable pieces for $25.00 to $30.00 depending on the specific retail audience
