Vintage irredecant color changing thick rectangle earrings

These were very hard to catch their colors changing in the house at 9:30 p.m so I just took a bunch of pics & out of all of them pic #16 caught their colors best as they sit without the light hitting them. They are something different & would look great with jeans. their main colors before the light hits are light blue, black, gold, silver & gray. They measure 1 7/8" L x just over 1/2" W & they are 1/4" thick. They're also loop pierced. New
