The color combinations shown on photo are only a few of the color combinations we create. If you would like to request certain colors please reach out to us via email wgkglass [!at] aol.com. The Aventurine glass in the belly is a glittery layer of glass that adds a magical and enchanting look to the hummer. You will be drawn for hours as it dazzles in the light.
