I shall call it "Brown Square in the ring".
I shall call this "Simply Purple".
For the moment, this will be "Rollie Pearlie".
The first and last ring was made by following instructions from the library book that I borrowed (Beautiful Beaded Rings). The 2nd ring was made following an online tutorial from here. I usually do not wear these accessories, esp after my kids are born. I like to make them though. Soon I will have lots of end products.
