18K Cartier Diamond Ruby Emerald Sapphire Ring

Like three celestial bodies adrift in a diamond constellation.

This sculptural ring by Cartier, crafted in France in 1980, is a masterwork of form and chromatic balance. Wrapped in a full pavé of brilliant white diamonds—approx. 4.0 carats in total—the bold gold setting curves fluidly across the finger, culminating in a triad of luminous cabochons: deep blue sapphire, velvety red ruby, and vivid green emerald.

A study in light, texture, and contrast, this piece embodies the maison’s late-century confidence—where opulence meets architectural clarity.
