Above, I've got on a French Jet necklace. I know it's French Jet because I tested it while I was there. It's an easy test that takes just a couple minutes and that anyone can do. I explain the whole process in another blog post so be sure to check that out. This necklace is super long and bling-y. It's easy to tie a knot in it like I show in the picture above.
Another great way to wear a long French Jet necklace is to make it shorter. Simply wind it around your neck and put one end through the other. That's the great thing about long necklaces. There are so many variations that look great with different outfits!
