This was the first time I had photographed a diamond, and what an incredibly hard job it was too. I had brought Mr Asscher near to a window so that I could get some natural light on the diamond. I sat him down on a dining room chair with his arms on the back rest to keep the diamond relatively still whilst I took the shot. The hardest part was actually trying to focus on the diamond. The auto focus was hunting all over the place and doing it manually I wasn't any better. In the end I focused on the fingers.
