Oscar Heyman 18k Yellow Gold Calibré Cut Emerald and Diamond Earrings Circa 1970

Precision, rendered in color.

These earrings by Oscar Heyman reflect the house’s uncompromising approach to gemstone calibration—where each stone is not simply set, but engineered into place. Composed as softly domed oval plaques, the surface is built from a tightly ordered mosaic of calibré-cut emeralds, their vivid green fields punctuated by round brilliant-cut diamonds placed with exacting rhythm.

The emeralds, totaling approximately 1.98 carats, are cut into uniform rectangular segments, each one fitted precisely into the gold framework to create a continuous, almost textile-like surface. Between them, diamonds—approximately 1.53 carats total—introduce light and contrast, breaking the grid with controlled brilliance rather than excess sparkle. The result is structured, balanced, and unmistakably deliberate.

Set in 18k yellow gold, the warmth of the metal enhances the saturation of the emeralds while softening the transitions between stone and light. The slightly domed profile gives the earrings volume without weightiness, allowing them to catch light from multiple angles while maintaining a refined silhouette.

At 14.1 grams, the pair has a satisfying presence, substantial yet wearable. This is classic Oscar Heyman—technical mastery concealed beneath apparent simplicity, where the discipline of setting defines the beauty of the piece as much as the stones themselves.
