Art Nouveau Era Old Mine Cut Diamond Solitaire Engagement Ring

This exquisite Art Nouveau engagement ring showcases a handcrafted mounting from the 1880-1910 era, featuring meticulous engraving and refined metalwork characteristic of the period. The two-tone design combines a green gold band—an alloy of gold and silver offering subtle elegance—with a white gold head that highlights the diamond's brilliance. At its center sits an old mine cut diamond, hand-cut between 1850-1920, distinguished by its unique faceting that produces a distinctive light reflection pattern. Unlike modern cuts with their uniform sparkle, Old Mine diamonds exhibit deep, intense flashes of light that shimmer most beautifully in natural and low-light settings. This authentic antique piece, over a century old, represents both historical craftsmanship and the timeless appeal of antique and vintage diamond jewelry.
