Bracelet Maker Identification: Understanding the 'R' Mark

Question
I am trying to identify the maker of a new diamond tennis bracelet that I was given.  The mark is a diamond shape with 2 capital letter R inside the diamond.  The first letter R is reversed so that it is a mirror image to the second letter R.  The bracelet looks nice but I am hoping to confirm if it is made by a good quality manufacturer.  

Thank you.

Answer
Hi Joanne, Sorry I am not fammiliar with this mark. It;s difficult with so many thousands of these marks out there.
There are some online mark publications for jewelry available on line and some mark publications in many local libraries.

Good luck !!
