How fun the house sale surprise! Stones come when we open to them, that's for sure. Amethyst feels so yum to me. The spirit quartz is usually smaller crystals whose sides are covered in smaller crystals, so they look furry. I have some that sit mostly in a group that get me smiling no matter what. They're over there beaming right now. ha!
Purple attracting you? A few other purple stones come to mind. Ametrine is amethyst and citrine together. I enjoy that energy too. Most comes from Bolivia, but not exclusively. I have three tumbled ametrines I enjoy carrying in my pocket. Charoite is my other most-used purple stone. It can be expensive, but tumbles are usually reasonable. Sugelite is a stone one of my friends lusts for! ha! Super magical stuff if it reasonates with you. Fluorite comes in many colors, including purple. It helps me stabilize my dreaming and integrate the usual human multiple personae into one calm package. Purpurite arrived a few years ago and I have yet to work with it much. Two tiny aquamarine crystals lie on it for now.
Fun with the smoky cluster. A smoky cluster can be extra grounding. Smokies help us see and embrace our shadow and dark natures, but more important to me is their adventurous, "trooper" attitude. No matter what we've done, no matter what's going on in life, they're beside us ready to help and play.
