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 our gemstones and metals. We use only the most exceptional colorless lab-grown diamonds, and craft each of your pieces individually. We are proud to be a part of the growing movement towards more sustainable and ethical practices in the jewelry industry.

Why nine? In Chinese culture, the number nine (九, jiǔ) shares its sound with 長久—meaning "long-lasting" or "enduring." It's a number that speaks to longevity, to things built to outlast fleeting trends. Nine is also the highest single digit—there is no ten. It's the score you aspire to, the grade that means exceptional. This is the standard we set for ourselves: Jewelry of the highest caliber, crafted to accompany you through a lifetime and passed down to generations after. Imagine slipping on a brilliant piece of Nine Carats jewelry to celebrate a life milestone, mark a precious moment, or simply reward yourself after months of hard work.

Nine Carats. With you through all of life's moments.
