Pink Opal 12 mm Rivoli by Matubo,
Rivoli do not have flat back, they are pointy on both sides and do not have a hole.
To use them in your jewellery designs, you will either need a metal setting, or you can make your own beaded settings, using e.g. peyote stitch.
Not all are the same, some may have more swirled/opal look to them and some have minor inclusions but they are stunning in person.
