This is just a stone and not a picture of a stone with a galaxy Photoshoped into it. Not a hologram made inside some piece of glass. Not a portal to another dimension. Just a stone. It’s like a some spacetime wizard captured a piece of the Universe and trapped it inside.
The stone is an opal and was sold for $20,000 at an auction house. Their description says that the 4.6 x 4.4 x 1-centimeter gemstone is a “clear, transparent crystal body having a fine, firey play-of-color that is gem quality. The piece has a botryoidal jasper formation which forms a unique inclusion.”
