The four C's of diamonds are easy to identify: Carat, Cut, Color, Clarity. The four C's of a brand? Maybe not so much. Here, we ask Pietra's jewelry designers to tell us what makes up their four C's: who is their dream celebrity? What is a common trait of all their amazing clients? What is the most prized piece from their collection, and what is unique about their craft.

CELEBRITY

Bella Hadid, Jennifer Lawrence, and Natalie Portman

CLIENT

A lot of them are also designers or artists; architects, photographers, textile designers, art teachers, journalists and people who work in fashion. Creatives.

COLLECTION

Under Earth Cocktail ring. I think this is my signature piece.

CRAFT

I like to experiment with materials, developing my own techniques to bring expressive forms to life in new ways.
