December's birthstones are Turquoise, Zircon, and Tanzanite! Turquoise, and the man-made alternative Turquenite, allows us to speak deep truths, connecting us to the larger cosmic story. Zircon, which can come in a variety of colors, is a stone of self integrity and helps you make larger personal transformations. Tanzanite is a psychic stone, allowing us to shift perspectives and even dimensions with ease.
