Here's a breakdown to help clarify:
If you're asking about a gemstone:
* Most gemstones are naturally shiny. They have a property called "luster" that describes how light reflects off their surface. Some have a very strong shine (like diamonds), others are more subdued (like matte opals).
* "Shiny" can also refer to a specific type of cut or polish. A well-cut gemstone will reflect light better than a poorly cut one.
If you're asking about a regular stone:
* Some stones are naturally shiny. Think of smooth, polished pebbles or certain types of rocks like obsidian.
* Others need to be polished to be shiny. This involves rubbing the stone against a rough surface to remove irregularities.
So, the answer is maybe. A shiny stone might already be shiny, or it might need some polishing to become shiny.
To give a more definitive answer, I need to know:
* What kind of stone are you talking about? A specific type of gemstone, or just any old stone?
* What do you mean by "shiny?" Do you want it to be sparkly, or just have a smooth, reflective surface?
