Aroma amber vs basic amber necklaces

Julie
Anyone used these aroma Amber necklaces? Do they work just as well as the basic Amber necklaces? All of it's Baltic Amber except those pink beads, they are optional to drip some essential oil on. Or just get the basic Baltic one? What's your experiences with either? She's 4 months old and having a lot of teething pain, so worth a try!
