I think the Fire Opal line from Sally Hansen gets overshadowed by the Nail Prisms. I think that is a shame because the Fire Opal line has some gems. I suggest wearing them layered over a darker color to make them shine. Earthen Opal is loaded with shimmer and has a dark red with hints of purple base and a bronze/brown flash of color. The duochrome quality is subtle but the twinkle shimmer isn't.
