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).
