Thanks.

Bob, the white jaggies were not a result of poor antialiasing 
techniques. Look closely and you'll see the antialiasing is really quite 
high because of the focal blur. Silly me, I didn't raise the resolution 
of the heightfield used to make the ruby (6 HFs & 2 planes, intersected) 
before rendering. By the time I noticed them, the render was already 
half finished :(
