The gradient patterns change from a value of 1 to 0 right at the edge of
your object's surface. In some places, it's coming up with a value of 1, and
in others 0, causing speckling.
You can fix this by either using sRadius = 0.9999, or by adding "translate
.0001" within your texture{} block (as opposed to outside of the texture
block, where it is now).
