The gemstone I found in my jewelry box - I must have gotten it on a field trip to a science museum in elementary school. There are so many beautiful stones at craft stores or even in nature that you could use to make a necklace like that.
I found the chandelier crystal at a flea market.
All you need is wire and chain, as well as whatever you want to use for pendants.
To create a pendant with a rock or stone that has no hole in it, wrap it several times with the gold wire and create a hoop on the top. For the chandelier crystal, wrap the wire through the hole, create a hoop at the top and then keep wrapping the wire around the top of the crystal.
Then, just put your newly created pendants on a chain.
Do you have any pretty stones or crystals that you've been wanting to make a necklace out of?
