Pizzazz! That's what genuine, gleaming onyx will add to jewelry designs. Such beauty costs a little more, and in this case, it's worth it. This material is highly polished striped onyx, dyed black in color. As the dye is accepted differently throughout the stone, periodic banding may still be displayed. Please be sure to rinse before stringing to avoid color bleed. From Brazil.
