{"product_id":"rare-ww1-allies-sweetheart-brooch-by-41891","title":"Rare WW1 Allies Sweetheart Brooch by Marius Hammer, Sterling Silver Enamel, Imperial Russia Included","description":"\u003cp\u003eAn exceptionally rare early WWI “Allies” sweetheart brooch by celebrated Norwegian enamel jeweller Marius Hammer, dating with unusual precision to 1914–1917. Made before the Russian Revolution of 1917 erased this exact alliance from history, it captures a remarkably narrow and fleeting moment in time.\u003c\/p\u003e\n\u003cp\u003eThe inclusion of the Imperial Russian Naval Ensign (blue St. Andrew’s Cross) is the defining detail. Following Russia’s withdrawal from the war in 1917, this design could no longer be produced, making Russia-inclusive examples far scarcer than later Allied flag brooches.\u003c\/p\u003e\n\u003cp\u003eThe composition is striking: four allied flags rendered in vivid enamel and arranged in a crisp cruciform formation around an open central square:\u003c\/p\u003e\n\u003cp\u003eTop: British Union Jack\u003cbr\u003e\nBottom: Imperial Russian Naval Ensign\u003cbr\u003e\nLeft: French Tricolour\u003cbr\u003e\nRight: Belgian National Flag\u003c\/p\u003e\n\u003cp\u003eThe reverse bears the unmistakable maker’s mark of renowned Norwegian jeweller Marius Hammer—a stylised “M” formed with a hammer motif—alongside a clear “STERLING” stamp. Hammer is internationally admired for his refined silver and enamel work, and the quality of craftsmanship here is entirely consistent with his workshop’s reputation.\u003c\/p\u003e\n\u003cp\u003eCondition is excellent for the period. The enamel remains bright and remarkably well preserved with no significant losses, while the silver has developed a soft antique patina. The original pin and C-clasp remain secure and fully functional.\u003c\/p\u003e\n\u003cp\u003eMeasurements:\u003cbr\u003e\n3 cm x 3 cm (1 1\/8 inches)\u003cbr\u003e\nWeight: 4.4 grams\u003c\/p\u003e\n\u003cp\u003eSweetheart brooches were deeply personal wartime tokens, often gifted by servicemen before departure. With its confirmed Marius Hammer attribution, Imperial Russian inclusion, and exceptional survival, this is an unusually collectible example that bridges fine Scandinavian enamel jewellery and early WWI history.\u003cbr\u003e\n___________________________________\u003cbr\u003e\nAt Mercy Madge we offer quality antique and vintage jewellery sourced in Great Britain.
