Create a hyper-realistic image of a lizard crafted entirely from gemstones and precious metals. The lizard's body is covered in a mosaic of sparkling gemstones, including rubies, sapphires, emeralds, and diamonds, creating a dazzling and colorful effect. The gemstones are embedded into a sleek metallic frame, mimicking the natural shape and texture of a lizard's scales. The lizard is positioned on a sunlit rock in a natural desert environment, with the textures of the rock providing a realistic and rugged contrast to the lizard's luxurious design. The background features softly blurred green foliage and earthy tones, enhancing the focus on the gemstone-adorned lizard. The lighting highlights the reflective qualities of the gemstones and metal, creating a mesmerizing blend of nature and opulence.
