Brazilian Cat's Eye Opal Cabochon
To our knowledge no more that 80 kilos of this rare variety of cat's eye opal have been mined in the last 30 years. This particularly rare green opal is found in veins in dark brown volcanic rock and the color is due to iron content. The present oval cabochon features a seam of chatoyant orange opal in its green matrix. This is the only location in which this particular type of opal can be found.
Weighing approximately 44.5 carats and measuring 26.5mm x 21.5 x 12.0mm
