A minimalist logo design for a jewelry brand, featuring two stylized koi fish elegantly intertwined with a gemstone. The koi fish are depicted in a clean, Flat Design style with smooth, flowing curves. The gemstone is subtly integrated into the design, either forming part of the koi fish bodies or placed at the center as a focal point. The overall composition should be sleek, sophisticated, and instantly recognizable as a gemstone and jewelry brand. The color palette is refined and harmonious, avoiding excessive details while maintaining a premium and luxurious feel.
