Overview

The charm is in the light: this appears to be a clear-glass wine goblet with broad optical ribs and a rainbow-like surface finish. Its gently flared bowl, shaped stem, and circular foot form an elegant silhouette; the owner reports a height of 6.75 inches.

Story

By the late 1800s, glassmakers were deliberately creating shimmering surfaces inspired by ancient excavated glass. Later tableware brought that jewel-like effect to the dinner table—turning an ordinary drink into a little light show.

Maker / Origin

The maker remains unidentified, with no readable marking visible in the supplied views. It belongs to a broad glassmaking tradition that combines optically textured forms with decorative surface effects.

Condition & Value

No obvious major cracks or rim losses are visible, but cloudy spots and irregular surface patches appear on the bowl and foot. Whether these are removable deposits or permanent surface changes affects resale appeal.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • ▲ Strong maker attribution with credible period details
  • ▲ Better-than-average condition for the category
  • ▲ Broader demand rises when presentation and finish feel intact

Concerns

  • ▼ Decorative-only demand limits the ceiling
  • ▼ Surface wear or missing provenance can compress the range fast
  • ▼ Regional sale lanes often underperform specialist venues
