Жемчужина — вариант 1

Use case: product-mockup. Use the supplied image as the exact reference. Create one isolated transparent PNG of one single lustrous natural pearl, a smooth nearly spherical cultured pearl with delicate subtle surface nacre. Explicit color: luminous warm ivory, soft champagne undertone, restrained iridescent blush-pink and faint pale blue highlights. Pose and angle: stationary round pearl viewed at the same slightly elevated three-quarter angle, with the main softbox reflection toward upper left. Framing: close-up macro product shot, complete pearl centered and filling about 75–80 percent of a square canvas with transparent padding. Preserve realistic satin-gloss nacre, gentle natural tonal variation and premium studio lighting. Make this sibling moderately distinct through warmer champagne-ivory body color and more visible rose-pearl iridescence on the right side, while retaining a natural ivory pearl identity. Genuine alpha transparency outside the pearl; no necklace, setting, surface, backdrop, external shadow, text or extra objects.
