We are Nine Carats

Nine Carats, founded in 2025, is a pioneering lab diamond jewelry brand. Driven by the passion to bring high-end, sustainable jewellery to customers worldwide, we are revolutionizing the fine jewelry industry by removing the traditional luxury markup without compromising on quality. Our unique creative approach skillfully blends decades of traditional handcraftsmanship with cutting-edge technological innovation, reflecting the background of our founders and setting our brand apart from others. Each of our pieces is made-to-order by our expert artisans in our workshop overlooking the Hong Kong harbour.

Fully committed to eco-conscious production—we are meticulous in selecting each and every one of gemstones and metals, using only the most exceptional lab-grown, colorless diamonds, and crafting each of your pieces individually to combat fast fashion. We are proud to be a part of the growing movement towards more sustainable and ethical practices in the jewelry industry.

Why nine? In numerology, nine is often associated with universal love and completion. This meaning is deepened by our roots: in Chinese culture, the number nine (九, jiǔ) sounds like the word "everlasting", making it the number most associated with eternity. For us, this concept of enduring love and permanence perfectly captures our diamond jewelry. Our name embodies our promise to create timeless jewelry of the highest quality, designed to last you a lifetime.
