This piece carries understated blue play-of-colour across this rectangular boulder opal. Painterly abstract forms run through this stone - every angle reveals a different composition. The ironstone host brings the opal face forward with striking natural contrast.
The stone weighs 25.83ct and is shaped to 25.36 × 15.62 x 5.94mm. Colour reads with an understated, refined quality - a stone with real character rather than showy fire. Fully natural and untreated - solid opal only, with no enhancements, no doublets, and no triplets. From the Winton region of Queensland, a heartland of boulder opal mining. Sourced, cut, and finished by our family - mine-direct from the earth to you.
A substantial piece best suited to a large pendant, brooch, or collector's display.
