Company History

L’Excellence is built on a legacy of understanding gems and a passion for fine jewellery. We are a family company with a unique heritage that encompasses every aspect of the gem industry, from mining to wholesale of diamonds and precious gems, and fine jewellery creation.

A family affair

Our story began in the 1950s

when Chinese-Thai entrepreneur Mr. Khau moved from China to Cambodia to create a thriving sapphire and ruby business in the country’s famous Pailin mines. By the 1960s, the Khau family became the owners of the largest gemstone mine and cutting business in the region.

L’Excellence began crafting fine jewellery in the 1970s, after the Khau family migrated to Paris, France. The company initially expanded into the wholesale business of precious gems and diamonds with reputable jewellers in the industry.

Then, immersed in the land of haute joaillerie, Mr. Khau’s son began fusing the family’s knowledge of diamonds and gemstones and sourcing process with the high standards of French craftsmanship to create stunning bespoke fine jewellery pieces.

Today, Mr. Khau’s granddaughters Sophie and Sylvie continue the marriage of refined French craftsmanship and the family’s diamond and gemstone expertise. L’Excellence welcomes its clients in its Raffles Place showroom in the heart of Singapore’s Financial District, with a magnificent view of the Marina Bay Sands, in addition to its Paris and Hong Kong offices, to cater to global clients.

Epitome of trust

Over the decades, L’Excellence has built up an excellent reputation that keeps clients coming back to create special pieces for self-expression or beloved symbols to honour their most significant life events.


Our Mission

We want to share our family’s enduring passion and deep industry expertise about fine diamonds, gemstones, and high quality French jewellery craftsmanship with the world.

We work closely with our clients to provide insightful advice that has been passed down from generation to generation. Our comprehensive knowledge of the industry permits us to craft and customise timeless fine jewellery pieces.

By attentively guiding clients through a bespoke journey, we help people tell unique stories and express their identities through jewellery. Enchanting tales of love are translated into engagement rings, wedding bands, and anniversary gifts, while other fine jewellery pieces are the result of self-expression, or are turned into precious family heirlooms. Your symbolic L’Excellence jewellery will become the most treasured pieces in your collection.
