I wish there were fewer art dealers. I wish there were fewer auctions. I wish there were just two auctions a year. It's just too much. And at the end of the day, if you're a dealer and a professional, fine, that's your business, that's all you do. But as an individual, if you're not a dealer and it's not your business, you need time for these things. You need time to study what's happening. You need time to understand the market. You need time to go to a museum. You need time to see a show. You can't go to one every day. It's becoming a trend.

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.

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.

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.

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

I think a lot of people are involved in art because of the fashion of art and the conversation. It gives them a certain sophistication, something to speak about. But art is, if it's conceptual, really about understanding the concept. And if it's beautiful, it's about seeing the beauty. It's gone much further than that now. There's too much commercialism attached to art. If the market cracks one day big-time, you'll frighten so many people away who will never come back. Because they don't really feel for art. People who buy art should want it because they love it, they want to enjoy it.

I can't draw. I can't paint. But what I can do is tell somebody else what to do. I'm a creator. I can tell an artist what to do. I can be behind the artist. I have the eye, so I can move things around. I can put stones together. I can match them.
