Meteorite, superb Boulder Opal, polished free-form piece from Queensland, Australia, weighing 37.85 ct (7.57 g) and measuring 42.7 × 14.4 × 7.1 mm, with blue, violet and emerald-green opal veins in a brown matrix.
AI-assisted summary
Description from the seller
This freeform-cut Boulder opal seduces with its elongated, almost fluid line, and with the elegant contrast between the brown matrix and the opal veins with subtle flashes. Splashes of electric blue, violet, and emerald green traverse the surface, like a luminous river trapped in rock. The gem seems to tell a geological story, where each colored vein evokes a millennia-old formation episode.
Originating from Queensland, this opal variety is sought after for its natural sturdiness and the graphic richness offered by the ferruginous matrix. Here, the harmonious arrangement of colors and the finesse of the polish give birth to a piece that is particularly balanced, suitable for both collection and artistic transformation.
