Overview

The item is a hand-blown green glass vase with an organic, undulating form. The base features a polished pontil mark, which confirms it is hand-blown rather than purely mold-made.

Story

This piece exhibits the classic characteristics of mid-century studio or production glass, likely dating from the 1950s to 1970s. The polished pontil confirms it was hand-blown rather than purely mold-injected. Without a signature or original foil label, it is currently treated as an unattributed decorative piece, though its form strongly echoes Italian (Empoli) or American (Blenko) design traditions.

Market Analysis

The secondary market for mid-century art glass remains robust, particularly for vibrantly colored, organically shaped pieces that fit well into contemporary interiors. Emerald green is a highly sought-after colorway, often outperforming clear or amber glass. However, buyers are increasingly discerning, paying significant premiums for verified makers (like Blenko or Empoli) while generic or unmarked pieces trade primarily on decorative appeal rather than collector value.

Value Drivers

▲ Vibrant emerald green colorway is highly desirable in current interior design trends.

▲ Hand-blown construction with a polished pontil signals higher production quality than mold-made equivalents.

▲ Organic, undulating form aligns perfectly with popular Mid-Century Modern aesthetics.

Concerns

▼ Unverified dimensions — if the vase is smaller than 10 inches, the estimate drops toward the $75-$150 floor.

▼ Lack of a verified maker's mark or label prevents tapping into the $500+ collector premium.

▼ Unverified rim condition — any confirmed chips or 'flea bites' would severely depress the value.

Best Venue

List the vase on a curated vintage marketplace like Chairish or 1stDibs if you can provide exact, substantial dimensions (height over 12 inches) to justify a premium decorative price. Ensure you take clear, well-lit photographs of the base and rim against a white background, and explicitly state the height and width in the listing to attract confident buyers.

Upside Potential

If exact measurements confirm a monumental scale (e.g., over 18 inches tall) or if an expert can definitively attribute the specific undulating form to a cataloged Blenko or premium Murano designer, the value could shift into the $500-$800 collector tier.
