Hi, I have been wearing blue


I have been wearing blue sapphire in my left ring finger, ruby in my right ring finger and Garnet in my right middle finger. But recently I came across an article that I am suppose to wear ruby in left ring finger (females). I also read that blue sapphire and ruby should not be worn together and also ruby and garnet. I am totally confused. I have the habit of removing the rings after i come back from work. Please Guide Me!!
