In 1957, the Soviet Union launched the Sputnik satellite into space, and designers found inspiration in the satellite craze.
This "Sputnik" bombé-style ring dates to the 1960s. The small sized Sputnik ring is 18k gold (unmarked, but acid tested) and studded with colorful gemstones.
The gemstone portion of the ring measures 0.5 inches in diameter making this smaller than most Sputnik rings.
It is currently a size 7, but it can be re-sized free of charge.
