Created by Boucheron Paris circa 1980s, this substantial ring is fashioned in 18k yellow gold and platinum, with a square-cut emerald weighing approximately 1.00 carat at its center. The emerald's saturated green is framed by four gold prongs and flanked by two diamond-set platinum panels, their cool brilliance providing a striking contrast to the warmth of the surrounding gold.

Above and below the central setting, broad bands of polished yellow gold are sculpted into a succession of rounded, closely spaced ribs. Their softly convex surfaces catch the light individually, creating a rhythmic play of highlights and shadows. The fluting continues around the visible shoulders, giving the ring a sense of architectural continuity and considerable depth.

The diamonds, approximately 1.10 carats in total, are arranged in compact settings on either side of the emerald. Their brilliance draws attention toward the central stone without overwhelming it. This interplay of richly modeled gold, crisp platinum, and concentrated gemstone color reflects the confident, sculptural character of Boucheron's jewelry during the 1980s.

Weighing 17 grams, the ring has a generous presence on the hand, its broad silhouette balanced by the disciplined geometry of the central setting.

A square of emerald green, held within the warm, undulating architecture of gold.
