Large green black opal, 3.95ct

One of the trickiest opals I've lately worked on - it has incredibly bright green broad flash but it's quite directional and should be set with great care to expose it the best way. This opal shows the brightest play of color while held up vertically, I would recommend to set it in the pendant.

• 3.95ct, 11.3x6.8x3.68mm, from Lighting Ridge, Australia.
• Brightness: 3 of 5, quite directional;
• Body tone: N3, Black opal.
