Magical 2.17ct Oregon Contra Luz Opal

Wanna see a magic trick?
Just add light and "presto!" This is Contra Luz opal from the opal butte area of central Oregon. Swipe left to see side-by-side photos with and without a light source.
Contra Luz means "against the light." While this opal still has some pretty color without being back-lit, the real magic is when you mount this in a bezel and can have it show off its amazing display of color against the light. 
This trillion shaped Contra Luz opal weighs 2.17ct and measures 11mm. It would look great in a ring or a pendant.
