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.

A mother-daughter trip to New York City's Diamond District took KBH designer Kimberly Berry Haisch by surprise: "I was resetting my engagement ring and they brought out lab grown diamonds. I was like, "Wait a minute. I don't want fake stones! I want real stones!" And my mother looked to me like, and was like, These are real! You can grow diamonds! My mind was blown. Why don't more people know this option is out there?”

Here, she gives us her Four C's.


Even before we launched the brand, I was over the moon that we had people that I followed and loved, like Molly Sims or someone like Melissa Wood, that wore our pieces. I'm blown away by the support we get already. But I would love for Michelle Obama to wear our pieces. She's such a strong female and cares about making the world a healthier place.


We have a range of amazing women buying our jewelry. Most of our clients are in the wellness world and are looking for a healthier option: a healthier world, healthier living overall. But it's always product first. I think half of the people find us because they love that we're sustainable and that we offer that option, but half of our clients find us because of the design. They see someone wearing a piece and then they find out we're sustainable after the fact. And I love that.


When we were launching, I think the only reason why we were able to kind of kick off in the way that we did and get to continue was because two of our products that launched right away just hit it. People loved it. They loved the design and then found out that it was sustainable. When the leaf climbers came out, the wave ring... those early pieces, we knew.


I wanted to create jewelry that serves as beautiful modern heirlooms, pieces that can be passed down to future generations. It is all about doing something for the world that my children are going to live in and eventually share with their own families. That is tradition; that is part of our legacy. Family, tradition and incorporating circular practices and sustainable materials are at the heart of everything we do and embedded into the fabric of our story.
