This is the real and rare Saphiret Art Glass which turns from tan to aqua and does Not have lines, as in similar color butterfly wings!
Have even seen jelly opal, dragon's breath, faux fire opal, all of which show flashes of pink, purple, blue, red mistakenly called by this name
This setting is mid 19th century and the bright odd faceted stones are either paste or rhinestones
