Mono Monday...........Best Friend

............................ diamonds are a girl's best friend, as Marilyn Munroe sang to us.  I am not normally a materialistic person, but I do have a weakness for diamonds, I love them especially this one, bought a couple of year's ago with an Insurance policy.  Of course I have some very good friends but it would be unfair to pick a best one, I value them all in different ways and for different reasons.
Thanks Dollykgray for hosting this mono challenge :)

Thanks so much for the lovely responses to yesterday's derelict image :)
