Mid-Century 5.25ct Emerald and 3.0ct Diamond Convertible Ring/Pendant, Platinum, Circa 1950s

A pear-shaped emerald anchors this platinum piece, its deep green color set within a ballerina-style halo of thirty tapered baguette diamonds that fan outward to echo the emerald's pointed silhouette. The baguettes graduate in size around the curve of the stone, a hallmark of fine 1950s ballerina settings that requires precise individual cutting for each position in the halo. The emerald's pear shape and the diamond halo's tapering rhythm work together so the eye reads the whole piece as a single continuous teardrop form. Practically, the setting converts between ring and pendant, giving the piece two distinct ways to wear the same stone. Stamped for platinum with 10% iridium content, a period-accurate alloy marking. Excellent condition; no visible chips or cracks to the emerald, though a gemological report is recommended to confirm treatment and origin before purchase. The center emerald weighs approximately 5.25 carats, while the accent diamonds total approximately 3.0 carats. Ring size: 5.75.
