Did you know Unicorns can cry?  It's an extremeley rare phenomenon, but it happens.  We are still unsure of the reasoning, but we were lucky enough to catch Unicoop shed a tear, when we went to wipe it from his face, it turned into this fossilized gem, which is now available to you.  Featuring a platinum filled tear on one side and Ow&Co. with Unicoop on the other.
