These huge Universe marbles are hard to come by these days, and this one is a doozy!! It is chock full of both opals and UV glass. One of the planets that used to exist in this Universe has already gotten sucked down into the vortex and been turned into beautiful crushed opal, and who knows how far behind the next two planets are. And it would be a shame, because those two planets are AWESOME, especially the blue and red one that glows pink under the UV light, sooo cool and SO much better in hand where that UV really pops! I love the UV in the vortex as well, and Gateson has added other UV highlights both inside and out. An opal moon floating on the edge of space tops off this magnificent Universe marble. Don't miss this chance to add this wild space gem to the collection! Signed 'Gateson 2018'.
