These are wonderful gifts for yourself or others. Can be placed anywhere in the home, office, garden, etc. People often hang them off the rear view mirror in their cars. These are genuine semi-precious stones. If placed near a window, they while capture the sunlight and create a number of rainbow prisms throughout the day. For those interested in Feng Shui or in dispelling negative or stuck energy, these sun catchers can be placed strategically around the house or office to create a more positive environment. Can also be used a dowsing tool. There is a loop at the top of the sun catcher which makes it easy to hang from a hook or nail.
