This exquisite pendant exemplifies the refined luxury of late 19th century Russian jewelry, combining precious materials with the technical mastery characteristic of Carl Fabergé's atelier. The piece features a luminous moonstone set within an elaborate frame of gold and guilloché enamel, the latter technique involving intricate engraved patterns beneath transparent enamel to create shimmering optical effects. Master craftsman Oskar Pihl, one of Fabergé's most accomplished workmakers, created this object around 1890 during the height of the Russian Arts and Crafts movement.
