While not part of the original construction, it now anchors the dramatic radiating composition and emphasizes the bold, graphic nature of the setting. The original design likely held either a large Old European Cut diamond or a richly colored gemstone such as sapphire or ruby, both commonly used in high-end starburst designs of the period.\u003c\/p\u003e\n\u003cp data-start=\"1347\" data-end=\"1750\"\u003eEncircling the center is a halo of approximately \u003cstrong data-start=\"1396\" data-end=\"1454\"\u003e1.00 carat total weight of antique single-cut diamonds\u003c\/strong\u003e, each set in individual prongs. These stones are consistent with late 1930s American manufacturing, where single cuts were the standard for fine accent work. Their presence in original settings provides strong evidence of authenticity, as modern reproductions would typically use full-cut melee.\u003c\/p\u003e\n\u003cp data-start=\"1752\" data-end=\"2089\"\u003eThe defining feature of this ring is its \u003cstrong data-start=\"1793\" data-end=\"1839\"\u003eradiating sunburst\/starburst platinum head\u003c\/strong\u003e, where elongated platinum “rays” extend outward from the center stone.

This architectural treatment is highly characteristic of American jewelry from approximately 1935–1942 and represents a shift toward the more bold, structured aesthetic of the coming Retro era.\u003c\/p\u003e\n\u003cp data-start=\"2463\" data-end=\"2755\"\u003eA \u003cstrong data-start=\"2465\" data-end=\"2480\"\u003esplit shank\u003c\/strong\u003e flows into the shoulder design, further reinforcing the transitional nature of the piece. This combination of structure, ornamentation, and volume is far more complex than earlier Art Deco designs, signaling the increasing influence of sculptural form in late-1930s jewelry.\u003c\/p\u003e\n\u003cp data-start=\"2757\" data-end=\"3170\"\u003eThe ring is stamped \u003cstrong data-start=\"2777\" data-end=\"2797\"\u003e“10% IRID\/PLAT,”\u003c\/strong\u003e an important and highly diagnostic hallmark of American platinum jewelry from the pre-WWII era. This designation indicates a platinum-iridium alloy, commonly used between roughly 1900 and the late 1930s before postwar standards shifted toward different alloy systems and “950 PLAT” markings became dominant. The presence of this stamp strongly supports a pre-1940s origin.\u003c\/p\u003e\n\u003cp data-start=\"3172\" data-end=\"3498\"\u003eDespite later modifications to the center stone and prongs, the ring’s underlying structure remains intact and strongly consistent with authentic late Art Deco American craftsmanship.
