Aha, so THIS is how gold is formed in the Universe!! An opalaic explosion brings elements together in its wake to form one of the most precious of all metals. A beautiful and very intriguing space scene in this one, a highlight for any collection.

The pictures aren't capturing it well, but the gold in the explosion is very metallic, and super sweet looking. This is the only Universe marble I've ever seen which has this feature (and I've seen a LOT of them, ha), making it a VEEEERY hard marble to let go of.
