A good place to start is tie tacks for men.

The pieces shown were created by using Bullseye fusible black glass.  The shaped piece of black glass was placed into a kiln.  Wonderfully colored dichroic pieces were cut and placed on top of the black.  Then a piece of clear Bullseye was laid over the dichroic.  The glass was fused to 1400 ⁰F. 
 

Next you might want to make broaches.  

The same wonderful dichroic is used in this small frog broach.  Fuse some wire into the piece
and put some small beads on the wire.  Finish by adding a pin bar to the back of the glass.

TIP: Use industrial strength E6000 glue to fasten all metal to glass or a good epoxy..

Use the same techniques to make earrings.   Choose either clip on or pieced ear findings.
Earring molds make it easy to make different shaped and curved earrings. 

Earrings make great Valentine Day gifts too.

You can also make necklaces by adding jump rings to a nice chain. 
Jump rings come in gold and silver, plain or with a spring ring.
