One side is set with finely cut calibré sapphires in a yellow gold setting; the reverse with old-cut diamonds set in platinum. The combination of yellow gold with sapphires on one face and the cooler platinum-and-diamond face on the other gives the wearer two distinct looks from a single piece — an ingenious and practical design that reflects the refined sporting culture of the Edwardian period. The use of both yellow gold and platinum in a single piece is characteristic of the transitional years of c.1910–1920, when platinum was becoming the preferred metal for diamond settings. French assay marks for 18ct gold; unknown maker's mark. Head diameter 1.13cm; pin length 7cm.\u003c\/p\u003e\n\u003ch2\u003eThe Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCirca:\u003c\/strong\u003e 1915–1920\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead diameter:\u003c\/strong\u003e 1.13cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin length:\u003c\/strong\u003e 7cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHallmarks:\u003c\/strong\u003e French assay marks for 18ct gold; unknown maker's mark\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eObverse:\u003c\/strong\u003e Calibré-cut sapphires in 18ct yellow gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse:\u003c\/strong\u003e Old-cut diamonds in platinum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e France\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wildsmith Jewellery","offers":[{"title":"Default Title","offer_id":55788965527936,"sku":null,"price":1450.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/2127\/0385\/files\/0141F940-12A5-4F3A-93FF-CBACFCCC651B.jpg?v=1742421663","url":"https:\/\/wildsmithjewellery.co.uk\/ja\/products\/edwardian-french-18ct-gold-platinum-reversible-sapphire-diamond-winning-post-stickpin","provider":"Wildsmith Jewellery","version":"1.0","type":"link"}
