Aurora Opal is one of my hands down favorites.  It is just magical.  Turn it in the light and the color shift will blow your mind.  This one is a long tear drop of pink Aurora Opal with shifts of yellow, green and orange.  Aurora opal is manmade in Germany.  This ring is set in fine and sterling silver with some hand stamping and sterling silver beads.  On a triple split shank for stability in wearing .
