This is a standard size for a small solitaire (single stone) decorative diamond. The balance of the prongs and setting also suggests a small diamond. Due to its small size, the visibility of inclusions may be low, and its clarity is estimated to be equivalent to SI-VS (no visible flaws to the naked eye). The use of a small stone with high clarity indicates careful craftsmanship for its time. The cut appears to be \"rose-cut style\" or \"Old European cut.\" Unlike brilliant cuts, it exhibits the unique light reflection of an antique piece (more sparkle than flash), and its aged luster is captivating.\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":42455449305172,"sku":"R070034","price":20000.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/3856\/4948\/files\/9-carat-gold-vintage-diamond-ring_0.jpg?v=1762316940","url":"https:\/\/adhocstore.com\/en\/products\/vintage-9ct-gold-diamond-ring-british-birmingham","provider":"ADHOCストアー","version":"1.0","type":"link"}
