Design a stunning nail art theme that captures the mystical allure of cat-eye gemstones. Imagine each nail shimmering with a radiant, multidimensional sheen, reminiscent of a feline eye glistening under moonlight. Use a magnetic polish technique to create an entrancing deep green and gold gradient that shifts as it catches the light. Integrate subtle, delicate details like fine line gold foiling or minimalist tiny 3D metallic elements to enhance the luxury vibe. The finished look should embody an air of elegant mystery and chic sophistication, perfect for anyone seeking to evoke their inner feline allure.
