Contemporary handmade marble. Made from borosilicate glass and the manipulation of 99.999% pure silver fume and particles. When the marble is almost complete it is allowed to cool to 1000 deg. Fahrenheit then is brought back up to a specific temperature. This action "strikes" the silver producing blues, greens, yellows and white. As with all the Silver fume space marbles the little specks that you see are not bubbles but small balls of pure silver.
A "net" of stars in the foreground with a bubble or sphere of stars in the background. A lensed spiral galaxy on the back.
It measures just shy of 1.5"
