This vintage mid-century ring features a bombé top crafted in platinum with five tiered rows of calibré step-cut emeralds alternating with round-cut diamonds. The stepped design continues fully around the heavy shank for a continuous, structured look. Set with 25 emeralds (approximately 2.20 carats) and 28 diamonds (about 0.85 carat), it is a US size 6 and is not resizable. Circa 1930s–1950s, it reflects streamlined Machine Age style through its balanced proportions and matched stones.
