Overview
This is a pair of beautifully detailed, molded and carved glass cabochons shaped like fancy goldfish, featuring a striking green and orange faux-opal fire effect. Mounted on their original export card with a distinctive 'TC' maker's mark, these pieces were manufactured in post-war Japan specifically to be set into high-end costume jewelry like brooches or earrings.
Story
Post-war Japanese workshops specialized in creating highly realistic glass imitations of precious stones. These whimsical goldfish were designed to mimic rare black opals, capturing the fluid motion of swimming fish for Western fashion houses.
Maker / Origin
The 'TC' logo on the card represents a Japanese export manufacturer or trading company from the mid-century era. During this period, Japanese glassmakers in regions like Osaka became world-renowned for their incredible skill in producing 'art glass' cabochons and imitation gems that rivaled natural stones.
Condition & Value
The glass cabochons appear to be in excellent vintage condition with no visible chips, cracks, or flea bites. They remain attached to their original paper backing card, which shows minor age-related yellowing and wear. Keeping them on the card preserves their premium value.
