KIERA was born in New York City from a simple idea — that fine jewelry can be beautiful, responsible, and lasting. Each piece is thoughtfully crafted with lab-created diamonds and recycled precious metals, combining modern innovation with timeless artistry.
At Kiera, we believe true luxury comes from intention — from knowing where your materials come from and how they’re made. Guided by this belief, we create jewelry that reflects light, care, and quiet confidence.
Kiera is for those who appreciate subtle brilliance — jewelry designed to be worn every day, cherished for a lifetime, and made with respect for both people and the planet.
