Description

Mined in the Outback of Queensland Australia this Opal comes from a small mining community near Quilpie, Australia

Boulder opal is a type of opal that forms within the cavities of ironstone boulders dating from the time when central Queensland was cover by an inland sea The Opal is found in both vertical and horizontal cracks or seams. It is cut with the ironstone remaining on the back and is classified as solid opal.

Boulder Opal occurs over a Vast area of Western Queensland from North of Winton to south of Quilpie. Boulder Opal is considered to be one of the most versatile opals because it has all of the colour and patterns of expensive black or crystals opals but it is contained within the iron stone which makes it extremely durable.

When looked at from the side you can always tell a genuine solid boulder opal by the natural uneven line where the opal filled the void in the boulder.

This opal shows some great color play of purples, reds and oranges as well as the more common blue and greens.
