He has since started plying his trade in France, leaving English outfit Sale to join Castres, while younger brother Jonny makes his own name for himself at Glasgow Warriors.
Jonny is one of five uncapped players chosen as part of interim Scotland head coach Scott Johnson's squad for the autumn internationals against Japan, South Africa and Australia.
Richie is among the other names selected and Jonny insists he is looking forward to catching up with his role model of an older brother in the coming weeks.
"Playing for Scotland is all you think about when you are younger and hopefully that will come and hopefully I will follow in Richie's footsteps," said Gray.
"People have said to me it will maybe be you and your brother one day and you laugh it off and say 'maybe' but you never think it will be true.
"Obviously I am delighted but I know I have a lot of work before I get there. Richie has always been a role model.
"When you look at what he has achieved in his career so far, it is what any player wants to do. This is an opportunity to train with him.
"I have not seen him for a while with him being in France and being with the Lions. So it will be good to be with him and I am really excited about it."
