Chopard co-president Caroline Scheufele works hand in hand with her brother to create beautiful and sustainable jewellery

A. We work very much hand in hand. He takes care of the men's world and I take care of the ladies' world. There are lots of positive sides to being a family-owned company. [One key point is that] we are our own decision makers, so everything is flexible and fast. We are also very free in terms of [creativity] - when we want to do something and we believe in it, we do it. That's a big plus.

The negative side of being family-owned [and not part of a big group] is that we may come across problems when looking for locations in new shopping malls or areas. But, so far, we've always managed to get the locations we want.

A. Even when I was a kid, I was always looking at my mum's jewellery. I still recall my very first design for the maison - the Happy Diamond Clown, which celebrates its 30th anniversary this year.

A. I've always been passionate about stones. I've always loved gemstones, diamonds and semi-precious stones. I like to play with colours and stones to create beautiful pieces.

A. With the Green Carpet collection and the partnership with Eco-Age, we have proved that luxury can be sustainable and the ultimate luxury is to know, no matter what your product is, how your product was produced and where the raw materials came from. We want to make sure children were not working in the mines and workers were paid a decent salary.

I believe sustainability is becoming more important, and I think the younger generation is [more aware] of the topic.
