Circa 1960. This platinum diamond eternity band features a continuous row of diamonds, each set within squared, geometric panels. The stones are secured in prong settings that allow light to enter from multiple angles, creating a bright, lively sparkle across the band. The diamonds weigh approximately .5 carats in total. 

Midcentury eternity bands often favor clean geometry and repetition over elaborate decoration, making them especially wearable today. Platinum examples from this period are prized for both their strength and their understated sophistication. The ring is approximately a size 6.75.
