I love matching earring and necklace sets. As far as I am concerned, you can never have too many.
I made the following earrings and necklace out of sterling silver for the earwires, wire hoops, and necklace hook, blue glass and zinc tube beads for the drops of the earrings, blue coral, blue glass, zinc tube beads and white seed beads for the necklace.
You cannot see it, as it is the back of the necklace, but I used a small length of sterling silver chain to make the necklace a variable length. I wear a LOT of blue and wanted to be able to wear this with many different styles of shirt.
