This authentic Murano Glass bead is part of our popular La Crima (tears in Italian) Line where little dots are pulled to look like tears. This is an approximately 14mm round with a crystal over .925 sterling silver base with black (which looks like chocolate and even amethyst as this is what black transparent does when thinned out). The bead has a 1mm hole through the center for making your favorite Venetian Glass Jewelry.
