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.

Futaba had one goal when creating a jewelry brand: to create a collection that mirrored the designer's personal goals: "to live minimally and simplistically while holding one's spiritual power in symbolic form close to oneself." Based in Brooklyn and raised in Japan, Futaba has created simple, yet graphic everyday pieces that you'll never want to take off. Here, her Four C's.

Men and women who are looking for unique, edgy and high quality pieces of jewelry.


Signet Rings. Each ring is carefully designed, and many of them had to go through a few rounds of trial and error both in design and production.


Many of our pieces have powerful symbols which are designed to empower the men and women who wear them. My graphic design background brings a clean, balanced look and helps to keep things cohesive to the brand. Edgy and playful pieces with minimal, elegant aesthetic and fine jewelry quality.
