3D frosted glass four-poi

3D frosted glass four-pointed sparkle icon on black background. The shape is a classic 4-point star with EXACTLY 4 tips pointing up, down, left, right. NOT 5 points. The tips are slightly rounded and the body is plump and thick. Frosted translucent glass material with soft matte surface, subtle inner glow, smooth yellow to green gradient blending seamlessly. Elegant premium quality, like Apple iOS icon style. Black rounded square background. No text. The shape resembles a plus sign with pointed ends, like a compass rose with 4 directions only.
