Magic Forums

Hello everyone, I'm fairly new to this stuff, so please excuse any missteps.

Yesterday, I've found a necklace in a forest by my house, and I began wondering if it had any sort of magic on it. I'm not a "natural wiccan/witch" as I've heard said every once in a while, so I can't say I "felt" anything when I picked it up. I was wondering:

1) Is there a method of detecting if an item is enchanted? I'd prefer methods with few materials, or ways of coaxing out that "feeling", but all methods are welcome and good to keep on hand - helps with a complete understanding and such..

2) Is there a way to identify what that enchantment is, or at the very least identify things about that magic, such as the intent, or "color"..

3) A more broad question, how exactly do enchantments work? What should I know before tackling this?

Thanks in advance for any and all input!
