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 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.

When there's an opportunity, some people pass it by. I've been lucky enough to recognise opportunities and every day, in my business, there's an opportunity somewhere - to buy, expand, design.

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.

Whatever nature gives us, we explore & we build on.

I'm attracted to the work of younger artists, and it's affordable compared to mature art, so you can take a chance much easier on a younger artist. I can't say that I've found an artist who I think is going to be the next Bacon or Warhol. You shouldn't have to do that really. You go forward, and you find something new.
