A 22.48 carat cushion checkerboard-cut natural purple amethyst measuring 18 x 18mm is double-claw set in an 18K yellow gold filigree gallery mounting with a two-tone white gold split shank paved with 36 round brilliant diamonds totaling 0.50 carats, weighing 11.00 grams. Ring face measures 18 x 25mm, size adjustable.

The 18K two-tone mounting is a masterclass in the vintage cocktail ring aesthetic — a warm yellow gold filigree basket lifts the massive 22.48 carat amethyst high above the finger on an open gallery of engraved scrolling floral and leaf motifs, visible in extraordinary detail from the profile view, while cool white gold split-shank fins descend from the basket on each side, each fin paved with round brilliant diamonds in milgrain-edged settings that add a crisp, sparkling architectural detail to the shank. The double-claw prongs at each corner of the cushion stone echo the Art Deco and Edwardian tradition of corner-held stones, while the filigree basket below them references the finest traditions of early 20th century goldsmithing — open metalwork that reduces visual weight while maximizing the stone's visibility from all angles. The deliberate contrast between the warm yellow gold of the basket and prongs and the cool white gold of the diamond-set shank creates a sophisticated two-tone tension that frames the purple amethyst's color with maximum chromatic impact.

This 22.48 carat cushion amethyst is a genuinely spectacular specimen — at 18 x 18mm face-up, this stone covers the full width of the ring face with a bold, uninterrupted field of vivid purple that commands attention from any distance. The cushion checkerboard facet pattern covers the stone's table with a grid of square facets that creates a mosaic of light reflections visible simultaneously across the entire crown, producing a visual effect that is far more dynamic than a conventional cushion brilliant and significantly more interesting than a standard flat-table cushion. The color shifts from deep grape-purple in the saturated interior facets to a warm rose-pink in the lighter peripheral zones, creating a natural color gradient across the stone's face that adds visual depth and three-dimensionality. Amethysts of this size and checkerboard cut with strong, clean color are increasingly sought in the cocktail ring market as alternatives to colored sapphires and tourmalines for buyers who want maximum color impact at an accessible price point.
