I want to buy my mother a gorgeous piece of jewelry for mother's day that is under $100. She has a great sense of style and likes ecclectic pieces. I think I have narrowed it down to these two. The first is an 18k Gold and amethyst bracelet from Joolwe.com. The second is a Delphine Nardine necklace (they didn't specify the stone) from Stylism.com Which one?
