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. If you're looking for a piece of jewelry made with passion, look no further than the pieces created by ISSAI, the Mexican designer whose passion for giving back to his heritage is equal to his passion for fine jewelry. By teaming up with local artisans to create the highest quality pieces, ISSAI is able to create beautiful, but more importantly, meaningful, works of art. Here are his Four C's.

The people that we work with have all been doing this for their whole lives and have learned from their families. It's a very traditional process. It's not industrial. It's handmade. We recycle our metal.
