Gemstone Tumblers are an easy way to keep your crystals near. Either in your pocket, bra (if you wear one lol) handbag, wallet, car, workspace the list goes on. I have an Amethyst & Smoky Quartz in my car for protection and calmness. Quite often in peak hour traffic, I have the Amethyst in my hand for calmness. I just chill out and remain calm. I always have one tumbler of some description tucked in my bra depending what I feel i need or am working on. Just trust in your intuition on where and how you would like to use your tumblers. There is no wrong way.
