Blue Black Opal, 1.88ct from Lighting Ridge, Australia green depending of angle and type1. 88ct, 13. 55x6. 73x2. 48mm, from Lighting Ridge, Australia. Brightness: 2. 5 of 5, moderately bright, directional; Body tone: N2, Black opal. An elegant deep blue Australian opal with quite a lot of character. I would recommend to set this opal in a ring because it's quite directional and will show off the best with movement. Please note that my camera is capturing more blue tones than is visible with human eye and colour is slightly more muted.
