3D icon of the number "1" made of transparent turquoise glass with subtle reflective surfaces and light refractions, standing upright in a single block font, the edges slightly rounded with a smooth cylindrical back spine that traces the contour of the number. The glass has a cool blue-green tint, realistic thickness, and smooth texture. The rendering should highlight the transparency and shininess of the glass while keeping the overall silhouette clean and iconic. The glass material should appear realistic with soft, subtle highlights and reflections to convey depth and dimension while maintaining readability as the number “1”. White background, centered, no shadow, clean icon style, high detail, 3D render.
