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.

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.

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.

Unfortunately, some of the young talants are becoming fashionable. And anything that's fashionable can become unfashionable. So one has to watch that. And it's very easy today because there are so many events - art fairs, gallery openings, etcetera. In fact, that's another thing that concerns me, the quantity of gallery openings. In my office in London, I get back after a week, and I have 30 invitations. It's too much.

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

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 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.
