This is a vintage hand-blown art glass egg-shaped paperweight featuring internal controlled air bubbles and subtle dichroic or iridescent accents, closely resembling studio glass works by artists like Robert Eickholt or similar mid-to-late 20th-century glassmakers.

At 3.5 inches tall, your paperweight falls right into the standard size category for standalone collectible studio glass sculptures.

Because it lacks a signature or label, it is classified as an unmarked mid-century style studio art glass paperweight. The specialized design technique used here creates a "jellyfish" or fountain effect, achieved by trapping a tier of teardrop air bubbles over a base layer of clear glass loops. Similar unsigned pieces typically value between $15 and $30 on platforms like eBay and Etsy
