Shop this category for Murano glass beads made with Effetre's amethyst colored glass. There are multiple shades of amethyst glass and each one looks different whether it is over foil or not. With Amethyst under 24kt gold foil it appears almost chocolate, while under sterling silver or white gold tends toward a brighter tone. For a more plum purple, try our Venetian glass beads made with blu inchiostro.
