Керамическое кольцо — вариант 1

Use case: product-mockup. Use the supplied image as the exact reference. Create one isolated transparent PNG of the same single thick sculptural ceramic torus ring, complete rounded donut form with a clear open center, same three-quarter view and centered square framing. Preserve the matte tactile ivory ceramic glaze, scattered terracotta and warm brown mineral speckles, soft upper-left studio light, realistic volume and generous transparent padding. Make a subtle color sibling: retain ivory as the dominant glaze and terracotta speckles, shifting a small portion of the speckles toward muted cinnamon-rose. Keep the opening, silhouette and speckle distribution natural and close to the reference. Genuine alpha transparency through the central hole and around the full object; no floor, plinth, backdrop, external shadow, text, logo, border, watermark or extra objects.
