An extreme macro product shot of a solitaire engagement ring from the invented brand Aurum Rue, a brilliant-cut lab diamond set in a slender platinum band with a delicate pave-set halo. The stone throws crisp rainbow fire under precise pinpoint studio lighting, resting on a black polished glass surface with a soft reflection. Deep dark backdrop for maximum sparkle contrast. Palette of icy white, platinum silver and black. Tight macro three-quarter angle. Ultra-luxurious fine-jewelry campaign mood, brilliant and precise.
