A beautiful example of Yowah Opal in matrix. This specimen is mostly Opal with a small amount of brecciated matrix mixed through. The colour ranges mostly in the orange / red, but there is also an amount of blue / greens throughout. The piece has been polished to highlight the spectacular colour, but has had no other treatments or enhancements.
An exceptional free form shaped specimen of Queensland boulder opal, with very bright multi colours of pastel blue green red orange on an ironstone matrix.
