A Precious Passion

About the founder

My name is Louis Lo, and I have been serving the gemstone and jewellery industry since 1967. Gems are my passion and I have devoted a great part of my life to them.

Before building BIRON®, I ran a thriving gemstone trading company for more than three decades. I am privileged to have shared my knowledge about gems with countless stone dealers, jewellery retailers, designers, and manufacturers around the world.

However, my journey towards lab-grown gems is not straight.

My Epiphany

In 2012, a leading lab-grown gemstone brand in North America asked me if I could source top-quality lab-grown emeralds for them. Until then, I hadn’t realised how difficult it was to consistently find lab-grown emeralds with the same quality as their mined counterparts. Driven by a desire to assist my clients, I decided around 2013/2014 to try to develop my own technology that could grow truly exceptional emeralds so that my clients can have access to top-quality lab-grown emeralds consistently.

My Epiphany

Growing A Dream


I began working closely with industrial chemist and geologist Artur Birkner who had more than 30 years of experience in geological exploration and mining and who was primarily responsible for developing what was known as the Biron process in the mid-1980s.  The name ‘Biron’ is actually a combination of the first three letters of Mr Birkner’s surname and the last two letters of the word ‘hexagon’, inspired by the hexagonal crystal structure of emeralds. Overcoming numerous challenges, we worked extremely hard to produce lab-grown emerald roughs of consistent quality that could meet the strictest demands of luxury brands. Together, we refined the Biron process and developed the formula behind the incredible quality of BIRON® emeralds.

A Rocky Start

As the saying goes, the days can’t all be sunny; some may turn stormy and dark. In mid-2015, I lost a significant deal when a key buyer decided to pursue an alternative line of business. This meant I couldn’t plan on where and how to continue my business for the next twelve months with any confidence. I wonder if you have ever felt that way – perhaps as a result of the COVID-19 pandemic. If you have felt anxious, depressed, lost, or frustrated in business before, I have been there too.

At the same time, however, I noticed reputable media outlets reporting increasing demand for more sustainable methods of / material for production, particularly among millennials. I found this to be in line with my dream of helping brands build jewellery collections featuring outstanding, genuinely sustainable lab-grown gems and my determination to do so was reinforced.

_A Rocky Start

A Brighter Future

A Brighter Future

Publications like Forbes, the BBC, the New York Times, the Wall Street Journal, the South China Morning Post, and more, continue to publish stories about how our younger generation is refusing to buy natural stones that are associated with high human cost and environmental damage. In 2020, a Mintel research report revealed that sustainability and ethics are top in the mind of 55% of UK jewellery buyers. That same year, Forbes reported lab-grown diamonds to be the fastest-growing category in the jewellery market.

I am convinced there is a bright future for lab-grown gems. Additionally, while lab-grown gems are known for their perfection, we can also grow gemstones with inclusions that resemble natural gems even more closely.

The Most Spectacular Lab Grown Gems

At BIRON®, I am proud to say that we have mastered the formula for creating what is known as Colombian green emeralds – the variety of emerald with the most sought-after colour. The BIRON® Process has made us the prime source for lab-grown Columbian-colour emeralds that meet the standards of world-class jewellers and luxury brands.

We apply the same standards of excellence to meticulously source lab-grown rubies, blue sapphires, padparadscha sapphires, alexandrites, diamonds, and opals, as well as other semi-precious stones for our clients. Thanks to our comprehensive collections, our clients can unleash their creativity to the full and create whatever they dream.

The Most Impressive Colour

After many years of intensive research on many aspects of hydrothermal technology,

BIRON® emerald resulted in a colour that was virtually indistinguishable from the Columbian Muzo emerald,

the most desirable colour in the marketplace.
