These quartz crystal necklaces range from $240 - $450.
Although I would love to own one of these, I forgot to write one in on this months budget. So I made my own.
I bought a small piece of quartz from the local jewelry store for a whole dollar and already had some metal wire around the house. I just wrapped the wire firmly around the quartz, twisted some things around, threw it on an old chain, et voila.
The result it slightly more organic than a designer piece, but you just can't beat the price.
Tip : Pick out a crystal that is a little distressed or disfigured at the top, this makes it easier for the wire to hold on. If you don't have any wire, a roll is only a few dollars at any craft store.
