The diamond displays a fancy light yellow brown color grade, giving it a warm, antique character that enhances its historic cut style, while the VS2 clarity ensures a clean appearance with only minor inclusions visible under magnification. The old mine cut exhibits a soft, cushion-like silhouette with deeper proportions and a romantic, candlelit brilliance typical of early 20th-century diamond cutting. Surrounding the center stone is a finely detailed geometric arrangement of 4 baguette cut diamonds and 18 single cut diamonds totaling approximately 0.30 carat, graded I-J color and VS clarity, adding structured linear sparkle and subtle vintage shimmer that enhances the ring’s architectural Art Deco design. The piece is crafted in platinum, offering a durable, naturally bright white setting that highlights both the warm-toned center diamond and the precision-cut accents. Originating from the 1920s Art Deco era, the design reflects classic period symmetry, contrast, and refined geometric composition. It bears purity marks along with maker’s marks, confirming authenticity and craftsmanship. Weighing 3.71 grams, the ring has a light yet elegant presence on the hand. It is currently a size 6 and can be resized for a proper fit. See less
