A simple line drawing of the zodiac signs, in black and white only, vectorized for a coloring book-style illustration. The sun is at the center, with each sign arranged around it at an angle. The shapes should be clear but without intricate details or shading to make them easy to color. There is no background, just flat white space all around. Each symbol must have one gemstone, with diamonds depicted as small gems, and their name written next to each symbol.
