Abstract Spiral Sphere Paperweight
Decorative Art / Glass Paperweight • Modern Studio Glass; likely School of Murano (Italy) or American Studio Glass movement.

Style & Movement
Mid-Century Modern / Contemporary Studio Glass Movement
Medium & Technique
Hand-blown glass; internal cane or ribbon techniques with color inclusions (cobalt blue and amethyst/pink) and internal air bubbles (controlled seeds).
Creation Period
Late 20th Century (circa 1970-1990)
Dimensions & Format
Approximately 3-4 inches in diameter; spherical format.
Subject Description
Non-objective abstract composition featuring a core of swirling blue and pink glass ribbons encased in a thick, clear crystal outer layer. The composition utilizes optical refraction to distort the internal linear patterns.
Condition & Value Assessment
Condition Assessment
Good; visible surface scratches and 'flea bites' consistent with age and shelf wear.
Estimated Market Value
$40 - $120 USD
Auction Estimate
$30 - $80 USD
Provenance History
Unknown; likely a retail or gallery acquisition for home decor. No visible signature or pontil mark is clear in the photo to confirm specific heritage.
Art Historical Significance
Represents the democratization of glass art during the Studio Glass movement, where techniques traditionally held by European masters (like those in Murano) were adopted by independent artists to create accessible, tactile sculptures.
Notable Features
Features a heavy crystal casing which creates a 'magnifying glass' effect on the internal cobalt blue spirals; presence of controlled air bubbles suggests a handcrafted origin rather than mass industrial production.
Condition Issues
Minor surface abrasions, light scratching on the contact base, and small internal air bubble inclusions (which may be intentional manufacturing artifacts).
Conservation Recommendations
Clean with a soft, lint-free cloth and mild soap. Avoid abrasive cleaners. Display away from direct high-intensity heat to prevent thermal shock.
