While in the past, the divas only wore their own jewelry, this is not the case now, says Boscaini.

"That's the charm of that era. Everything was elegant but natural ... In the past stylists simply didn't exist. Elizabeth Taylor, Ingrid Bergman and Grace Kelly took care of their own styles, according to their personal tastes ... Today everything is guided by business rules and fashion rules so it's completely different. But it's a revolution. There is no bad or good," she says.

The brand's heritage collection now has about 760 pieces of iconic jewelry, which have been sourced from auctions, dealers and through personal networking.

"We look for jewelry that represents a specific kind of style in terms of shape, volume, color, material and craftsmanship ... Even when the design is different, you can recognize some common elements in the style," says Boscaini.
