You learn about yourself when you're collecting art. You learn what you're capable of. After all, we're not speaking about pennies-we're speaking about vast sums of money. I do it on my own back without advice, so I've got the confidence to do it.

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

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.

Art is like an avalanche being poured down your throat. You know it's going to crack, eventually it's going to go out of fashion. I wish there was much less happening. I wish there were fewer art dealers. I wish there were fewer auctions. I wish there were just two auctions a year.

It's the rough diamond that dictates what you can get out of a diamond. You can't say, "I'm going to make this," or, "I'm going to make that." It's nature. Whatever nature gives us, we explore and we build on. We can't create something that is not in the stone, so we take away as many imperfections as we can. Sometimes, you can't take them all away. But mostly, our cut, our polish, the life we put into the stones, the beauty that we bring out is exceptional.

Your eye becomes more mature. What you don't see the first time, you keep looking, and eventually you'll see it. And when you are confident with what your eye sees, you know you've got to have it.

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.
