It seems some unknown entity captured a small slice of the universe and trapped it inside of the stone.
The piece has a botryoidal opal formation which forms a unique inclusion
The stone pictured above weighs approximately 119.0 carats and measures, and was found in Opal Butte, Oregon. Despite the beautiful swirling colors, what makes this piece really unique is the brown nebula-like cluster formed inside it.
Bonhams describes the stone with dimensions of 4.6cm x 4.4cm x 1cm. Bonhams also claims the stone is clear and transparent with a crystal body having a fine, firey play-of-color that has the quality of a gem. Lastly, the stone has a botryoidal jasper formation, forming an inclusion that is unique.
