Multiple hallmarks can be found on the inside of the ring, indicating that it was made in Birmingham, England, in the 1970s (375 = 9-carat gold). \"N\u0026amp;G\" is likely the maker's hallmark, suggesting it was crafted by a skilled workshop of that era. It comes with a classical navy blue antique-style case, making it an ideal gift. The ring is approximately a Japanese size 19, making it suitable for men or those who prefer larger sizes.

Opals from Lightning Ridge and Coober Pedy in Australia, in particular, were known for their beautiful play-of-color and were extensively exported to the European market. Queen Victoria herself favored opals, leading to an explosion in popularity among the upper classes. Australia was a British colony until the 19th century, with active trade in precious metals and gemstones. Australian opals were highly regarded, even called \"the jewels of the British Royal Family,\" and were frequently handled by London jewelers. Around 1970, with the return of classic styles and the resurgence in popularity of colored stones, opal rings and brooches became fashionable again. Australian white opals were commonly used in British jewelry from this period.\u003c\/p\u003e\n\u003cp style=\"text-align: right;\"\u003e\u003cem\u003e*Based on AI research.\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"イエローガレージ","offers":[{"title":"Default Title","offer_id":42455082434644,"sku":"R070032","price":38000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/3856\/4948\/files\/australian-white-opal_0.jpg?v=1762316340","url":"https:\/\/adhocstore.com\/en\/products\/vintage-opal-ruby-ring-british-9ct-gold-1970s","provider":"ADHOCストアー","version":"1.0","type":"link"}
