Wilhelm Buchert - Artist's bangle with star sapphire and brilliant-cut diamond Design: Wilhelm Buchert (1939, Zwickau – 2023, Kiel). One-of-a-kind piece. 900/- yellow gold, unhallmarked, tested. Total weight: 67.2 g. 1 star sapphire in cabochon cut (D. 0.97 x 0.97 cm). 1 brilliant-cut diamond, approx. 0.08 ct (tw/vsi). Inner dimensions: 5.1 x 5.7 cm. Latch clasp. In good condition. This solid bangle, crafted from high-karat gold, is accented by a cabochon-cut star sapphire. The gemstone’s unique optical phenomenon, known as asterism, appears as a star-shaped reflection of light on its domed surface when viewed under the right lighting conditions. A small brilliant-cut diamond complements the setting and adds a subtle touch of sparkle. The combination of this rare optical phenomenon with the unique goldsmithing underscores the one-of-a-kind nature of this piece of jewelry.
