tolkiens legendarium - Why were the Elvish Rings of Power not made by Sauron?

Among all the rings of power, the 3 rings possessed by Elves are special in that they (unlike Men's and Dwarves' and The one) were made by Elves and not Sauron.

Why?

As in,

• 
  

  Were they made before Sauron conceived of the idea of making the Rings and controlling them with the One?

  
  
  


• 
  

  Were they made before Sauron knew HOW to make Rings of power, by Elves on his request so that he could learn the process?

  
  


• 
  

  Were they made because Elves didn't trust him and preferred to roll their own modules instead of downloading from CPAN?

  
  


• 
  

  Other?

Answer

Looking at the LotR wikia article on Celebrimbor, it appears he made all the rings, the sixteen under the guidance of Sauron, and the Three in secret, on his own.

During the Second Age, [Celebrimbor] lived in the Elvish realm of Eregion. Under the guidance and instruction of the Dark Lord Sauron, who feigned good intentions, calling himself Annatar, the "Lord of Gifts" — Celebrimbor openly made sixteen rings: seven for the dwarves, and nine for men. But secretly, without Annatar's knowledge, Celebrimbor created the three Rings of the Elves, the greatest and fairest of the Rings of Power. These rings were thus free of Annatar's corrupting influence.

So, it basically was that Celebrimbor wanted to roll his own kernel rings.
