Pinterest Logo in Transparent Water Sphere

Create a premium ultra-realistic CGI render of a floating transparent water sphere containing a volumetric Pinterest logo. The sphere is made of clear flowing water with realistic refraction, light bending, and physically accurate liquid behavior. The water surface is smooth with subtle air bubbles inside and small water droplets on the outside. The Pinterest logo is fully volumetric with precise shape and proportions, featuring rounded geometry, a red base with a white symbol, and is slightly submerged in water. The logo is covered with tiny air bubbles and micro water droplets, with clean smooth edges and no extra text or typography. The scene features premium studio lighting with soft but clear highlights, natural light diffusion through water, and a subtle diffused shadow beneath the sphere. The background is a neutral gray studio setting with a smooth gradient, no texture, and no objects. The image is ultra-realistic, high-end advertising CGI with HDR, high contrast, perfect clarity and depth, and centered composition. The lighting is abstract with no people, environment, or studio equipment reflections. The overall effect is serene, modern, and visually striking, emphasizing the Pinterest logo within the transparent water sphere.
