Antique Art Nouveau Diamond Engagement Ring 14k

This Art Nouveau solitaire engagement ring features a .35 carat old mine cut diamond with SI2 clarity and I color set in a two-tone combination of 14 karat white and yellow gold.

The old mine cut produces a chunky, romantic sparkle with a higher crown and smaller table than modern brilliants, characteristic of hand-cut diamonds from the late 1800s and early 1900s. SI2 clarity means inclusions are noticeable under magnification and may be visible to the naked eye, while I color shows faint yellow warmth.

The geometric mounting holds the diamond securely while creating angular lines typical of the Art Nouveau period (1890s-1910s). Hand-engraved orange blossom motifs cover the band, blending floral and geometric elements that defined this era's aesthetic. The two-tone gold construction creates color contrast between the white and yellow metals.
