Phenomenal Welo Opal Cabochon from Ethiopia. Large stone with lots of fire!
Welo opals are renowned for their vibrant and dynamic play of colors, which is caused by the diffraction of light as it passes through microscopic silica spheres within the opal. This phenomenon produces a mesmerizing display of colors that can include hues of red, orange, green, blue, and more. The play of colors is highly sought after and is the primary factor that determines the opal's value.
These opals formed in volcanic rocks, and their origin is believed to be associated with volcanic activity in Ethiopia.
