SIZE: 26 x 18mm weight: 2.83 grams material: platinum gemstones: natural diamonds 1.60ctw, SI-I, H-I chain not included Notes from the Curator This open-heart pendant displays one of the most enduring configurations in platinum jewelry: round diamonds held in a shared-prong setting that traces the outline of the heart itself. The open heart represents an open heart ready for love, vulnerability, and honesty, and the design gained particular traction in the late twentieth century as jewelers sought forms that balanced symbolism with wearability. At 26 millimetres tall and weighing nearly three grams, this example sits comfortably in the mid-scale range—visible without dominating the collarbone. The 1.60 total carats spread across multiple round brilliants rather than a single center stone creates continuous sparkle along the frame, and platinum's neutral white lustre ensures that the H-I colour grade of the diamonds reads cleanly. The shared-prong technique, in which a single metal claw secures two adjacent stones, keeps the metal presence minimal and allows maximum light to reach each facet, a construction favoured for maximising brilliance in outline pendants.
