I went to a job and sat down as a proper apprentice, learning how to make jewelry. It involved a lot of remodeling and repairing. It was a bad time in England in those days and people didn't have much money - they would repair a ring rather than buy a new one. They would thicken up the gold. I learned all the ways to make something look new again.

I was always a little bit of a collector and a hoarder. And whenever I got involved in anything, whatever it was - even when I was a kid and I collected cigarette cards - I really got into it and had the most. So when it came to paintings, once I got the bug, I always wanted to buy something. But I really knew nothing about art.

I went to an auction in the late '70s and bought a small Renoir. People said, "Why did you buy a Renoir that size?" I said, "I can put it in the safe with my diamonds." And that was a true story. I bought it to put it in the safe.

I always believed, right from the beginning, if you're going to do something, do it the best. If you're going to work, you want to enjoy it-make a product that you really enjoy selling or owning.

One of the great things about collecting contemporary art is that you mix with contemporary people.

The Graff Hallucination is a sculptural masterpiece; a celebration of the miracle of coloured diamonds. For many years I have thought about creating a truly remarkable watch that illustrates our all-consuming passion for diamonds. The Hallucination has made my diamond dream a reality.
