Glass pendant measures 1.5 inches diameter. About Holograms: Holograms are created by using high-powered lasers to record a 3D image of an object within a special photographic film. The image is not an optical illusion or a trick, like lenticular & stereoscopic images. A hologram is a real 3-dimensional photograph & acts like a window where you can view the object from various angles. When light is shined on the hologram, microscopic ridges & patterns within the film reflect light back toward the viewer, recreating the image that was originally recorded. There are many different types of holograms, & they can even contain multiple separate images that are viewable from different angles. Other types of holograms will have color-changing properties or the appearance of movement.
