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. Testing for colorfastness is recommended.
