To make them begin by extending a paper clip. Make a small tight bend at one end. Roll the wire continuously around the bend to create a coil. Make sure you wrap the wire so the existing paperclip bends are hyper extended.
Use cone nose pliers to separate the coils. Keep separating until you have a platform just big enough to set the crystal. Trim the coil down to size and file off any sharp edges.
Place the crystal on top of the coil and use a heat gun to activate the adhesive.
