1.35ct Blue Cuprian Opal, Andes Mts

1.37ct Blue Opal, Copper bearing, Andes Mountains

10.2 x 4.6 x 4.1 mm

A uniquely shaped and well colored Blue Opal, colored by Copper.  Very clean and perfect for a petite pendant or as an accent stone in a larger piece (looks especially striking next to pink).  This material has become very difficult to find in this quality range in recent years. In some light these Opals look a bit more green, but blue is the dominant hue most of the time (last picture).
