Professional e-commerce studio photograph of a solitaire engagement ring from the fictional jeweller Lumeyra: a 1.5-carat oval lab-grown diamond held by four claw prongs in a low cathedral setting, on a slim 1.8 mm knife-edge band in polished 18k yellow gold. The ring stands upright on its band, seen from a three-quarter angle slightly above, so the diamond's table and the side profile of the setting are both visible. Seamless pure white background (#FFFFFF). Soft, even softbox light from both sides with a white bounce card overhead, a small soft contact shadow directly under the band. Crisp facet sparkle with natural black-and-white contrast inside the diamond; the polished gold reflects white with thin dark edge lines that define its shape. 100mm macro lens look, f/11, the whole ring in sharp focus. The ring fills about 80% of the frame, centered. No props, no hands, no text, no logo, no watermark.

Image 1 is the product: a Lumeyra oval solitaire ring in polished 18k yellow gold. Keep the exact design from image 1: four claw prongs, the low cathedral arches under the head, the oval diamond's proportions and the slim knife-edge band. Do not add side stones, a halo or engraving. Extreme macro detail shot of the ring's head, camera just above the band line looking across the diamond, so the four prongs gripping the stone and the cathedral arches are the subject. The ring rests on a sheet of pale grey brushed aluminium that fills the whole background; the far edge of the band falls out of focus. Small hard spotlight from top left for strong fire and sparkle in the diamond, fill light bounced from outside the frame so the gold stays bright; no cards, reflectors or other objects visible in the frame. 100mm macro lens look, f/5.6, focus on the front prong. No hands, no text, no watermark.

Image 1 is the product: a Lumeyra oval solitaire ring in polished 18k yellow gold. Put this exact ring on the ring finger of an adult woman's left hand. Keep the ring identical to image 1: four claw prongs, low cathedral setting, oval diamond pointing along the finger, slim plain knife-edge band, same yellow gold colour. The ring must sit on the finger at a realistic size: the diamond is about as wide as the finger, not larger. The hand rests lightly on a cream linen cloth, fingers relaxed and slightly apart, back of the hand toward the camera, the wrist leaving the frame at the bottom. Natural skin texture with fine lines and visible knuckle creases, short rounded nails with a sheer nude polish, exactly five fingers. Soft window light from the left, gentle shadow to the right. 85mm lens look, f/4, focus on the diamond. No other jewellery, no text, no watermark.

Close-up jewellery photo for a product page: an adult woman in her early thirties wearing a fictional Lumeyra pendant necklace. The pendant is a 12 mm round disc in brushed 14k yellow gold with three engraved wavy lines across it, hanging from a fine 1 mm gold cable chain that sits just below the collarbones. Framing from the chin to the top of the chest; the face is cropped out above the lips. She wears an ivory silk camisole with thin straps. Warm, natural skin with visible texture and a few freckles, not airbrushed. Soft daylight from a window on the right, gentle highlight on the brushed metal, the chain links crisp. 85mm lens look, f/4, background a soft warm beige blur. The pendant hangs straight and faces the camera. No other jewellery, no text, no logo, no watermark.

Overhead still life of a pair of fictional Lumeyra huggie hoop earrings: small 12 mm hoops in polished 14k yellow gold, each with a single 7 mm freshwater pearl drop hanging from the bottom. The pair lies on a slab of honed travertine with natural pores, next to a loosely folded strip of sand-coloured silk ribbon and a small open ring dish in matte white ceramic. Late-afternoon sunlight from the top left casting long, crisp shadows of the hoops and pearls across the stone. One earring lies flat, the other is propped on its edge so the hinge and the pearl's lustre are visible. The pearls are slightly irregular, with soft pink-silver overtones. 100mm macro lens look, f/8, both earrings sharp. Earrings take about a third of the frame, placed on the left third, warm neutral colour grade. No text, no logo, no watermark.

Image 1 is a Lumeyra oval solitaire ring, image 2 is a pair of Lumeyra pearl huggie earrings, image 3 shows the Lumeyra wave-engraved disc pendant on a fine gold chain (use only the necklace from image 3, not the person). Keep all three pieces exactly as they appear in their images: same gold colour, same prong setting and band on the ring, same hoop size and pearl shape on the earrings, same three engraved wavy lines on the pendant. Keep their real-world sizes relative to each other: the ring's diamond is 9 mm wide, each earring hoop is 12 mm across, the pendant disc is 12 mm across, about the same width as the ring's head, and the chain is a fine 1 mm cable chain, thin as a thread. Arrange them as a gift set inside an open square jewellery box, 9 cm wide, lined with oatmeal-coloured suede: the ring standing upright in a slot at the centre, the earrings pinned side by side in the top-left, the necklace chain coiled in a loose circle with the pendant facing up at the bottom right. The lid stands open behind, its inside lined with the same suede and blank. The box sits on a warm white plaster surface. Soft daylight from the left, gentle shadows, 50mm lens look from about 45 degrees above, all three pieces in sharp focus. No text, no logo, no watermark.
