Like the name of this marble? My apologies if you don't, but it's a dichroic galaxy style marble, and I had the movie Guardians of the Galaxy on my mind, ha ha. AWESOME movie. Anyway, back to marbles...and speaking of dichro and galaxies, this one is AMAZING in that regard. You truly need to see it in hand, and then you'll see that the dichro is PERFECT, filling up the entire marble below the lens, and flashing super bright reddish gold and green colors as you rotate it. Sweet example of this tech, and then the backside is just as killer, with that gorgeous sparkly pinwheeling. A classic Sable gem right here, signed 'Sable 2006'.
