Fluorite is known for absorbing negative energy and stress, and also increasing the power of concentration, self-confidence and decision making. The fluorite stone is 1/2" x 1/2" and hangs on a 1.8mm brown leather cord that can be adjusted from 14" to 24". You will receive the necklace shown in the picture.On request, I will send in an organza or burlap gift bag. In order to extend the life of your necklace, I recommend removing before showering or swimming.Thank you for stopping by my shop!Rebecca :)
