Overview

A charming pair of champagne coupes featuring a wide, shallow bowl and a thick, sturdy stem. The glass is treated with a metallic vapor finish that creates a 'petrol' or 'oil slick' iridescent glow across the surface.

Story

Iridescent glass was once the height of luxury, pioneered by Tiffany to mimic the oxidation on ancient Roman vessels. These 20th-century revivals brought that ethereal, rainbow-like magic to the everyday dinner table.

Maker / Origin

While these lack a visible signature, they follow the tradition of companies like Fenton or Mikasa, who popularized 'Luster' finishes. This specific chunky stem design suggests a more modern, mid-to-late century production intended for celebratory use.

Condition & Value

The pieces appear to be in good vintage condition with the iridescent finish intact. The presence of a thrift store sticker suggests they have been handled, so check for 'flea bites' or tiny chips along the rim. Condition is standard for age. Value is based on the current trend for 'Grandmillennial' and iridescent decor.

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
