Hello everyone. I am going into a career in histology, so I am somewhat involved in the sciences. As such, one of my friends asked me the other day if I could have a chunk of any pure element, which element would it be? I happen to think Sulfur makes beautiful crystals, I love their brilliant yellow-green color. After answering that I would like a Sulfur crystal, I went about checking the possibility of making it happen. Turns out Sulfur is pretty easy to get your hands on. I have a Sulfur crystal now, and I am exploring ways to turn my crystal into a piece of jewelry. Now I am by no means a chemist, so this is why I ask the following question. I am looking at getting it made into a necklace at a local bead shop and having the crystal encased in a copper wire cage. However, I know sulfur oxidizes most metals, and I know for certain that Sulfur reacts with Copper to create Copper Sulfide. What I can't figure out is this: Does the reaction to create Copper Sulfide require heat, or will it happen if the two elements come into contact at room temperature? I'm worried that making such a necklace out of solid copper and solid sulfur would produce a reaction that would ruin both my crystal and the copper wiring. Another idea I had was using copper wiring that has already been oxidized to changed the element into a new compound that may not react with sulfur with the added bonus of the copper wiring having a nice blue-green coloring. I am assuming the product of copper oxidation is known as Copper Oxide. I can't seem to find anything on the internet that would suggest Copper Oxide and Sulfur react, but I can't find anything on the internet that suggests they won't react either. So I registered here to ask this question and see what people who are better at chemistry than I think of the feasibility of my envisioned sulfur necklace. Any feedback is much appreciated.
