Which of the top five high-end gemstones in the world is named after an animal?

1. Elephant Trunk Stone

2. Cat’s Eye Stone

Correct answer: Cat's Eye

Cat's Eye is often called the "noble gemstone". Because the light phenomenon exhibited by cat's eye stone is the same as that of a cat's eyes, it is flexible and bright and can change with the intensity of light, hence its name. Together with alexandrite, it is one of the world's five most precious high-end gemstones (the world's five most precious gemstones are diamond, ruby, sapphire, emerald and cat's eye).
