Cleaner and Bigger

With the availability of cleaner and bigger gemstones at an affordable price, your customers will love to commission you to make statement pieces.

In 1985, a report by the Gemological Institute of America (GIA) confirmed that a lab-grown emerald produced with the hydrothermal process was exceptionally clean and large. This method is significantly better than the flux melt process, which almost always produces flaws or inclusions. The report results still remain valid today.

Colombian Green

Green is the colour of life, peace and harmony. Emerald symbolises growth, energy, and fertility. Its rarity makes it a popular option for engagement rings.

With the persistent effort of our technical experts, the BIRON® process has been advanced and the most sought-after colour Colombian Green is now more readily available. Characterised for the bluish-green to green colour with intense saturation, the gemstone has been beloved by royals, celebrities, and fashion icons from ancient to modern times.

Beauty is in the eye of the beholder. What makes the inner world of minded Colombian emeralds fascinating are the three-phase inclusion (liquid, gas, and small crystal).

The hydrothermal process is a relatively expensive process because it requires high levels of heat and pressure to mimic conditions deep down in the Earth’s core. By carefully adjusting the production formula, inclusions can be recreated. lt is worth the expenses because the gems grown with this process offer incomparable results.

Meet the Founder


I still remembered the day when the US-based sustainable jewellery retailer came to me and sought my help urgently.

I am Louis Lo — a gemstone specialist who is passionate about promoting sustainable gemstones for a better world.

My journey to sustainable jewellery got started in 2012 when 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.  The manufacturers I encountered always:

  • over-promised, under-delivered;
  • lack proactive communication about quality;
  • lack visibility on the real status of sourcing;
  • not willing to spend time trying to fully understand my requirements.
  • not committed to quality control and assurance.
Driven by a desire to assist my clients to procure top quality lab-grown emeralds consistently, I began my journey on making lab-grown gemstones and now have helped 500 gemstone dealers from five continents to enrich their offerings, and have sold over ten tonnes of lab-grown gems across the globe. Come join me in our own Save the Future Movement and let’s make history together. [Read More]

FAQs on Lab Made Gemstones

Are lab-grown emeralds fragile and easy to break?

Lab-grown emeralds sold under the BIRON® brand are always of the most superior quality and are less brittle than their natural counterparts and are therefore less susceptible to breakage. Other lab-grown gems are sourced by us based on our 35 years of experience in the gem industry.

Will BIRON®gems lose their sparkle over time?

The composition of BIRON® lab-grown gems is almost identical to their natural counterparts. These are “real” gems, not fake ones, which are simply grown above the ground rather than underneath through processes that mimic the conditions of nature. BIRON® gems withstand the same wear as all precious and semi-precious stones.

How do you ensure your gems are consistently of the finest quality?

Our ability to provide the finest quality lab-grown gems comes from three areas:

Technology – Emerald roughs we grow are of premium quality because of our ability to adjust the formula for nutrients which makes clear Colombian Green Colour possible and add, if desired, inclusion to the gems resulting in a very close, if not identical, appearance to natural gems when judged by human eyes.

Craftsmanship – every gemstone is cut, multi-faceted and polished by hand.

Strict quality control – We are one of the few remaining factories in the world that still conducts 100% quality control checks of our gems before they are shipped to our clients.

How long will it take to get my lab-grown gems?

Our delivery time takes around three working days if we have the gems in the dimensions you desire in our collection, and 7-28 working days if a bespoke item is required.

  • ln stock gems: 3 Days
  • Cutting and polishing service: 7-14 Days
  • Sourcing, cutting and polishing: 28 Days
