Opal Size Chart
Boulder Opal Parcel from Queensland Boulder, Australia.
Just look at the amazing colors of the smaller boulder that is included within this parcel of two. Stunning green, yellow, orange, red and blue colors shine out off this undulating face which is 26 x 11.5mm in size.
The other is 38x18mm, has a nice cabochon cut and a very interesting strip of potch that goes almost through the center of the opal. The colors beautifully shine out through different depths of the stone with beauties like red, orange, yellow, blue, purple and pink appearing.
