What necklace do you like best, and why?

I like # 2, 4, 5, and 7. However, I am not a fan of yellow gold and am a fan of Swarovski Crystals. But for one on a budget, the ones without Swarovski Crystals would be the best choice. I would be likely to get any of the ones listed and I very well might after seeing those choices. Those necklaces are rising in popularity so you'd be looking at a wide crowd wearing them. It might not take off like skinny jeans or big sunglasses but it will be seen more often. haha
