Answer and Explanation:
The chest looked ancient - I would have guessed some good hundred years. There wasn't much to it; no golden adornments of any kind. Its wood was dark, damp, and splintered, as if it were telling the story of every storm, every high tide, every humid summer it had survived. There was a sort of metal strap around it, with rusty little hollowed handles that closed side by side to allow the padlock to lock. The padlock itself was rusty and rustic, with a huge black emptiness in its center waiting for a key - the majestic old key I now had in my hands. I felt as if electricity were running through my veins instead of my own red blood, as if my brain could no longer contain any thoughts other than the curious urge to open that chest. I did it carefully, afraid to hurt my hands with the rusty iron and the splinters. Inside, there was nothing but a necklace. My heart thumped strongly, I would have heard its beating in a vacuum. I had found it, the golden necklace everyone believed to be a myth. I held it in my hands, triumphantly.
Note: Your question does not give much context about how or why those objects would be found. So I just made up some sort of story around it. Feel free to change anything!
