Akro made a Carnelian that glows like the dickens, they were marketed by the Akro company with this name. (as shown above by Chad)
There is also one by Akro called Carnelian Oxblood, a collectors name I believe, these have no glow.
I believe that MFC marketed bricks as Carnelians, I am not so sure about this one though. It has been awhile since I have seen a box of those.
Someone correct me if I am wrong here.
MarbleāOn!!
