Fluorite is a stone for balancing, particularly said to balance the brain, the creative right brain and the analytical left brain. Rainbow fluorite specifically is said to help with harmonizing the heart with the mind, ensuring your words, thoughts and actions are aligned with the heart, allowing you to manifest in the 3d world what it is your heart desires. It is also said that if you meditate with fluorite it can bring rich visions & insights. It represents the element of wind & is thought to balance all chakras not just one specific energy center in the body.
These lamps are made from natural fluorite from the hills of China. They come with a small LED wood light that has a switch and plugs in via USB. See last photo for what the ceiling looks like when I have it plugged in. It weighs 1 lb and measures about 4.5 x 2 x 2 iches.
