This is a vintage pink or peach art glass paperweight featuring a dense cluster of suspended controlled air bubbles (bullicante style) and a rounded shape.

The estimated market value for an unsigned, vintage 3.25" pink bullicante (controlled bubble) art glass paperweight generally ranges between $15 and $35.

Unsigned paperweights with this style of trapped bubbles are commonly categorized as "Murano style" or mid-century studio glass. Similar 3.25-inch vintage controlled-bubble orbs regularly sell on secondhand platforms like eBay and Etsy within this bracket depending on condition: 

• $15 – $25: Standard market price for an unmarked, nice-quality piece with minor shelf wear on the base.

• $25 – $35: Premium value if the glass has excellent optical clarity, a perfectly flat polished base, zero surface scratches, and a highly symmetrical bubble configuration
