Thank you for all the positive comments folks.
I would like to say that I modelled the diamond but I didn't.
It is the one that Henry very kindly posted in the other gold ring thread.
I used the facet editor to change the seating for the diamonds to mercury material.
Photoscape was used to add the lens flare and to correct the balance in the picture as the original looked a bit dull.
Original posted for comparison.
Edit: Almost forgot.
This is the first time I have managed to get the HDRI and light probe to work.
