Precious Opals

These opals are known for their enchanting play-of-color, a unique phenomenon where shining spectral hues dance across their surface when it is exposed to light.  These opals are cherished for their iridescence, which is caused by the presence of silica spheres which are arranged in a specific geometric pattern within their structure. This arrangement causes light to diverge, creating a display of colors that can include shades of orange, green, blue and even red. 

What sets precious opals apart is their exceptional beauty and rarity. Usually found in volcanic or sedimentary environments, these rare geological conditions add to the formation of their distinctive play-of-color.
