The 21st Ring of Power?

I also believe that Saruman was imitating Sauron. It's obvious that he had a long curiosity about the dark arts, which gradually turned into desire for power.

Here's a question. Both Saruman and Sauron were originally of the people of Aule. I know that Sauron was the probably the mightiest of the Maiar, but how is it that his craft is so far beyond Saruman's? They were both about the same age. Saruman stayed in Valinor while Sauron was in Middle Earth with Melkor. More than likely, that gave Saruman more time in the presence of Aule. It seems that he would learn more of forging from Aule than from studying Sauron evil from a distance. Was it that Sauron invented the lore of Rings of Power? or was it that Saruman did not really become interested in rings until coming to middle earth?
