This is a vintage dome-shaped art glass paperweight, commonly featuring a clear crystal or colorless glass dome encasing multicolored "confetti" or pulled glass shreds in shades of blue, white, black, and green. Pieces in this style are often attributed to mid-century or vintage production methods, such as Italian Murano-style or general studio art glass "end-of-day" confetti designs.

An unmarked vintage paperweight of this style is typically valued between $20 and $55 on the secondary market.

Because it is unsigned and lacks original labels, its value is driven by decorative appeal rather than a specific collectible brand or artist name. Similar "end-of-day" confetti scramble or spatter glass designs routinely sell across platforms within these ranges: 

• $15 – $30: Standard value for smaller, unmarked vintage studio pieces with minor surface shelf wear.

• $30 – $55: Value for larger, exceptionally clear, or well-executed pieces in the style of Murano or Gentile Glass
