Amethyst, the February birthstone, is top of my list (along with Citrine which is essentially the same, but that’s another story). It is probably one of the most distinct and recognizable of stones. It is a calming stone that offers balance and peace and is a sobering stone that helps to articulate problems and practical solutions. Amethyst rules the crown chakra and is a highly spiritual stone. It is great for anyone working to build personal wealth, growing their business, or fostering love which is why it is said to be the stone of happiness and contentment. My favorite partially because it is my birthstone, I can honestly say I have not gone without it in over a decade!
