LONDON--Fashionista by birth, painter by training, jeweler at heart: Natasha Collis is a soft-spoken brunette who seems she will forever be 23. The daughter of creative director of Browns, Caroline Burstein, and granddaughter of boutique founder, the legendary Mrs. B., Natasha has quite a reputation to live up to. Yet the petite jewelry maker has found her own path: tucked away on the Northern end of Ibiza, in a 400 year old studio, she spends day and night making tiny, one-off jewelry pieces. Based in St Miguel, a village full of artisans, her lifestyle is light-years away from the reputation the Spanish Island has for all-night boozing. And her jewelry reflects this: no bling, no loud nonsense nor flashy logo. Only intimate, delicate arrangements.
