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.
