A women's ring, detailed and decorative, moderately ornate. High-end fine jewelry photorealistic rendering of a single 1.90 carat marquise-cut diamond mounted east-to-west on a 2.0 mm wide, perfectly flat 18k yellow gold band. The diamond should dominate the design and appear almost visually unsupported from the front. tiny rounded talon-like tips that wrap only the extreme points, with the gold transition occurring underneath/behind the diamond. Use only two extremely minimal, integrated yellow-gold point claws at the east and west tips, hugging the stone's outline as tightly as physically possible. No visible basket, gallery rail, halo, bezel, shoulder prongs, decorative metal, or side stones. The band should transition directly into the two point claws, with structural support concealed beneath the diamond's pavilion. Keep the diamond's entire face-up outline unobstructed. The setting should be low-profile and suitable for everyday wear, with realistic diamond pavilion depth, realistic gold thickness, and physically plausible stone security. The result should look like the diamond is floating over a simple flat gold band while remaining structurally believable. Clean contemporary luxury jewelry, understated, architectural, minimal, no ornate details. The two point claws should be exceptionally small and refined—just enough metal to securely capture the east and west tips. They should visually disappear into the diamond rather than look like conventional prongs. Use a continuous, smoothly tapered transition from the flat shank into each claw, with no upward hooks, bulbous shoulders, decorative curves, or obvious mounting structure. Any additional structural metal necessary to support the 1.90 ct diamond should be positioned underneath the pavilion and hidden from the face-up view. Show the exact same ring and diamond in three views: straight-on face-up view, 3/4 view, and true side/profile view. Maintain identical diamond proportions, orientation, band width, setting architecture, and scale in every view. The side view must show a realistic pavilion clearance and physically plausible support beneath the stone. Do not invent a floating or unsupported construction. The diamond is mounted east-to-west and secured only at its east and west points by two minimal yellow-gold claws. Photorealistic high-end jewelry product photography, accurate jewelry construction rather than conceptual fantasy. Use the exact proportions of a true marquise-cut diamond: elongated, sharply pointed east and west tips, distinctly narrower than the current rendering, with a graceful continuous curve from tip to tip. Do not make the diamond oval, cushion-like, rounded, or overly wide. Preserve realistic marquise proportions for a 1.90 ct stone.
