So that is just what I did. I took the necklace home, and I took all the jump rings apart to separate all the pieces. See the tag (below)-I only paid $2.97 for this awesome necklace.
Then I took a single gem thingy, attached chain to either side, put a clasp in the back, and now it's a lovely simplistic necklace. And, I hung two gems from short pieces of chain and attached them to earring hooks.
Now I have a a simple matching jewelry set to wear for date night!
And, since there were 12 total gems on the original necklace, I was able to make a total of 4 necklaces,
1 pair of earrings, and have 6 gems leftover for other projects....and an empty gem setting I have no idea how to use at this time ;) Plus I still have the gray ribbon closures to upcycle later.
