- Opal shells are very unique pieces for any collection. These are shells that have been opalized. A lot of these shells come from the opal fields in Coober Pedy while the more valuable black varieties of these options are found in the Lightning Ridge area. Originally, the opal fields in Australia formed along the bottom of a large inland sea.
