For all info on the Clear Rocky Road glass including measurements and feeling of textures go to my review at link
I will have a review for the Gold-Fumed Rocky Road in the near future
On the bottom of the base on the Clear Rocky Road is the Phallix logo which is actually etched into the glass. Being that the glass is clear and the etching is a faint white it doesn't show up good. It's like looking down a glass well...
However the same logo is etched on my Caterpillar and since it's green glass shows up much better
I hope this clears up the differences between the two dildos.
