I am writing this review only a day or two after getting two very nice diffuser necklaces for aromatic essential oils. I wear them a lot so far. The necklaces are stainless steel with a nice chain each. Very sturdy and well made. I tried lemon with frankincense and I find myself smelling my necklace in inconspicuous moments. The scents are light and refreshing. I will learn enough to choose another healing oil for me and see how that goes but now I know why oils are such a big thing now. Its very pleasant to carry the scent with me too.
