Little squares filled with rainbow colors, for your ears!  Crafted in 14 karat white gold, these studs hold a pair of natural opal doublets.  Doublets are composed from a slice of genuine opal, supported by a slice of iron stone matrix (the material opal is mined from).  The studs feature square bezels and posts with luxury weight friction backs.  The studs measure 3/16 of an inch in diameter.
