"Generate a jewelry set consisting of a necklace and a matching stud earring, described in full detail below: NECKLACE: A sterling silver chain necklace, 41cm in length with a 5cm extension. The pendant hangs from a small polished teardrop-shaped bail. The pendant itself is a round, faceted gemstone measuring exactly 2cm in height and 0.8cm in width, cut in a distinctive spiral 'rose flower' pattern — meaning the facets spiral inward toward the center like the swirled petals of a rose, rather than a standard round brilliant cut. The stone is set in a simple four-prong setting that grips the outer edge of the stone at four points. EARRING: A matching stud earring featuring the same round spiral rose-flower cut gemstone, exactly 0.6cm in diameter, set in the same four-prong setting, attached to a standard silver post and butterfly backing. STONE COLOR: the gemstone is cubic zirconia in a soft lavender-purple color — light and delicate, not deep violet or magenta. The stone must sparkle realistically, showing multiple internal light reflections and brilliance typical of a high-quality faceted gem, with the spiral cut clearly visible as concentric swirling facets when viewed head-on. METAL: sterling silver, rhodium-plated — bright, cool-white, reflective, with a polished mirror-like shine. Not yellow, not matte, not dull. PRESENTATION: flat-lay product photography shot from a slight top-down angle, on a bright, clean white background — pure white to very light off-white, not cream or beige. Include a few subtle decorative elements placed naturally around the jewelry to add texture and elegance — such as a small sprig of dried or fresh greenery, a soft draped piece of light white/ivory satin or silk fabric, or a delicate small flower petal or two scattered nearby. Keep the decor minimal and tasteful, not cluttered, so the jewelry remains the clear focal point and the background stays predominantly white. The necklace chain is draped naturally in soft loose coils to one side, with the pendant resting flat and clearly visible. The earring is placed neatly beside the necklace, facing forward so the spiral cut pattern is visible. Lighting: soft, bright, even studio lighting with gentle natural shadows for depth. Composition: elegant and airy with balanced negative space, sharp focus on all jewelry details, true-to-scale proportions exactly as described (pendant 2cm x 0.8cm, earring 0.6cm), professional high-end e-commerce product photography style.
