Create a square luxury macro product photograph of an {argument name="jewelry type" default="emerald solitaire ring"} staged like precious botanical alchemy. Place one ring centered in the lower-middle of the frame, resting horizontally on a curled glossy green leaf that forms a shallow cradle. The ring has a polished yellow-gold band, four rounded gold prongs, and one vertical oval-cut {argument name="gemstone" default="deep emerald green stone"} with crisp facets and internal sparkle. Surround it with exactly three large background leaves or petals: one curved green leaf sweeping from the left foreground toward the ring, one curled green leaf rising on the right edge, and one blurred burgundy-red petal mass in the upper background. The surface beneath is wet black volcanic stone or lacquered rock, with small puddles and mirrorlike highlights. Add visible water droplets on the leaves and rock, including several bright beads near the right leaf and tiny specks on the left leaf. Lighting should be dramatic and cinematic: warm golden rim light from the upper right, soft frontal reflection on the gemstone, deep shadows, high contrast, shallow depth of field, luxurious editorial jewelry advertising style. Use a dark moody palette of emerald green, yellow gold, burgundy, and glossy black. Camera angle is close-up at leaf level, 1:1 square crop, ring tack-sharp while background petals and foreground edges fall into creamy bokeh. No text, no hands, no packaging, no extra jewelry, no logo, no watermark.
