Sri Lankan scientist-innovator Milinda Edirisinghe introduces AI-integrated gem testing system to gemological world

Published

In a country celebrated for producing some of the world’s finest gemstones, Sri Lankan gemologist Rewatha Milinda Edirisinghe now says the future of gemstone testing must move beyond traditional observation and into the realm of scientific precision powered by artificial intelligence.

Edirisinghe, the Founder and Managing Director of Gemological Report of Ceylon (GRC), has introduced what he describes as a next-generation AI-integrated spectroscopy system designed to modernize gemstone identification and analysis for global gem laboratories.

The innovation, currently under patent application in Sri Lanka with plans for international patent registration, combines a traditional gemological spectroscope with smart-device connectivity, proprietary algorithms and an AI-driven gemstone database capable of analysing mineral compositions with unprecedented precision.

According to Edirisinghe, the invention was born out of a longstanding frustration shared by many gemologists.

“The spectroscope is one of the most powerful tools in gemology, but it is also one of the most uncomfortable instruments to use,” he said during an interview with The Island Financial Review. “Even experienced gemologists often avoid using it extensively because it strains the eyes and requires difficult interpretation of colour absorption patterns. For colour-blind users or those with eyesight limitations, it becomes even more challenging.”

A conventional spectroscope allows gemologists to study how gemstones absorb light, revealing unique spectral signatures linked to trace elements such as chromium, iron and vanadium. These spectral patterns function much like fingerprints for gemstones, helping experts identify species, treatments and origins.

Edirisinghe’s solution transforms that traditionally manual process into a digitally assisted scientific system.

Using a specially designed clip-on device attached to the spectroscope, spectral data from gemstones can now be transmitted directly to a smartphone or smart device under varying lighting conditions and viewing angles. The collected data is then processed through dedicated software and algorithms before being matched against an AI-supported gemstone database developed in collaboration with foreign partners, including specialists in Thailand.

“The spectroscopy is the fingerprint of a gemstone,” Edirisinghe explained. “What we have done is create a system that captures those fingerprints more accurately than ever before and analyses them scientifically through AI-supported comparison.”

The system, branded as the “Ray’s Spectroscopy System for Smart Devices,” named after his middle name Rewatha, is designed to identify gemstone treatments, detect enhancements and even assist in determining the geographic origin of stones.

He says the innovation marks a significant shift in how gemstone certification could evolve globally.

“In many laboratories, reports are sometimes issued mainly based on surface-level tests such as specific gravity or refractive index measurements. Those methods are important, but they are not enough for comprehensive gemstone identification in today’s complex market,” he noted.

“With this system, gemstone analysis becomes a deeper scientific exercise rather than simply issuing a certificate after limited testing.”

Edirisinghe believes the technology will also democratize access to advanced testing by offering laboratories a more affordable alternative to costly imported systems.

The GRC founder is no stranger to challenging conventions within the gem industry. Earlier this year, his laboratory gained industry attention for introducing rigorous multi-layered certification methodologies aimed at elevating Sri Lanka’s standing in international gemstone authentication markets.

Now, with his latest innovation, Edirisinghe says he hopes to position Sri Lanka not merely as a source of valuable gemstones, but also as a contributor to global gemological science.

He draws parallels between his contribution and that of the late Francis Leo Danvil Ekanayake, who discovered the rare radioactive mineral ekanite in Sri Lanka in 1953.

“After the discovery of ekanite, there have been very few scientific innovations emerging from Sri Lanka’s gemological sector,” he said. “I wanted to contribute something practical and globally relevant to the industry.”

While commercial production awaits patent approval, the system is already being used internally at GRC’s laboratory in Colombo. Meanwhile, the database continues to expand with fresh gemstone data and analytical inputs from international collaborators.

For Edirisinghe, the ambition extends beyond business success.

“If Sri Lanka is known for producing some of the world’s finest gemstones, then we must also contribute world-class scientific innovation to the industry,” he said. “That is how we truly elevate Sri Lanka’s name in global gemology.”

Development deficit getting in the way of SL joining RCEP – Trade Ministry Secretary

Published

Principal panelists at Pathfinder Foundation forum.

Sri Lanka is not quite ready to join the Regional Comprehensive Economic Partnership (RCEP), since it is lacking sufficient development, Trade Ministry Secretary K.A. Vimalenthirarajah said.

‘At present the Trade Ministry is establishing Sri Lanka’s readiness to join RCEP, which consists of 15 countries, through several channels, Vimalenthirarajah said at a recent round table discussion titled, ‘Sri Lanka’s Pathway to RCEP and the Emerging Global Trading Order’, organized by the Pathfinder Foundation and held at the Colombo Club, Taj Samudra.

‘Sri Lanka is actively accelerating its compliance efforts to join the 15-nation RCEP having submitted its required accession questionnaire in early 2026, he explained.

Vimalenthirarajah added: ‘The Cabinet has established a high-level policy and working committee and also obtained some technical assistance from multilateral partners because complying with RCEP requirements is challenging. Subsequently, this body responded to the follow-up questions that came up and had discussions with RCEP representatives and it expects more follow-up questions with regard to Sri Lanka’s readiness to join RCEP.

‘Sri Lanka has also secured political and diplomatic support from current RCEP members, including Australia, New Zealand, and Indonesia, to facilitate its entry process.’

Meanwhile, state officials, including Industries and Entrepreneurship Development Deputy Minister Chathuranga Abeysinghe, are implementing key economic structural reforms, a new tariff policy, and transparent investment criteria required by the bloc. Because formal accession protocols for RCEP are still being finalized, Sri Lanka is also simultaneously negotiating bilateral trade and investment agreements with regional members to accelerate integration.

Abeysinghe, participating virtually in the event said that Sri Lanka cannot achieve sustained export growth and attract large-scale investment by relying solely on its domestic market. ‘As a small economy, the country’s future lies in deeper integration with regional and global value chains. RCEP connects 15 economies, including Japan, South Korea, Australia, New Zealand, China and ASEAN member states, collectively accounting for nearly 30% of global trade, he explained.

Abeysinghe added: ‘Access to such a market would create new opportunities for Sri Lankan businesses, particularly the country’s Small and Medium Enterprises (SMEs), which currently contribute only around 10 percent to national exports.

‘However, Sri Lanka is at least a decade behind in implementing many of the reforms required to fully participate in modern global trade. Recognizing this challenge, the government is now moving forward with several critical reforms: A new tariff policy to improve competitiveness and eliminate barriers to trade, transparent and predictable investment criteria, investment facilitation reforms to improve the ease of doing business, new legislation including the Public-Private Partnership (PPP) Act and SOE reforms to strengthen investor confidence and measures to improve investment protection and unlock new sources of capital, including venture capital and angel investment funds.

‘Sri Lanka’s exports currently stand at approximately US$ 17 billion and have grown only gradually over the years. Expanding market access through bilateral and multilateral agreements, while continuing domestic reforms, is essential if the country is to achieve its long-term economic ambitions.’

Roshan Ranawake, Managing Director of Control Union Sri Lanka, presents the certification to Philip J. Wewita, Chairman of Pussalla Agri Ventures (Pvt) Ltd, in the presence of Dr. Chamindi Jayasooriya, Director, and members of the Pussalla Agri Ventures team.

In a landmark development for Sri Lanka’s organic spice sector, Pussalla Agri Ventures has been awarded both EU Organic and USDA Organic certifications for its premium Ceylon cinnamon products. The certifications were officially conferred at Control Union Sri Lanka, signaling a major milestone in the company’s strategic transformation toward fully certified organic operations.

The recognition strengthens Pussalla Agri Ventures’ position as an emerging exporter of certified organic products, with its flagship offering, organic Ceylon cinnamon (Cinnamomum verum, also known as Cinnamomum zeylanicum), cultivated in Sri Lanka’s traditional cinnamon-growing regions.

Notably, the dual certification opens doors to some of the world’s most lucrative and compliance-driven organic markets, including the European Union and the United States.

Pussalla Agri Ventures began its structured transition into organic cinnamon cultivation several years ago, building a fully integrated system covering cultivation, processing, and value addition. The company currently manages extensive cinnamon cultivation lands and operates under strict organic agricultural principles, ensuring compliance with global certification standards.

These certifications, issued through Control Union Sri Lanka, validate that the company’s farming and processing systems meet rigorous international requirements, including restrictions on synthetic chemicals, comprehensive traceability controls, and environmental sustainability practices. These certifications add to an existing portfolio that already includes SL GAP, Food GMP, and Cosmetic GMP certifications.

Company representatives described the achievement as a “milestone” in the Pussalla organic journey, one that paves the way for expanded access to premium export markets in Europe and the United States. According to them, the certifications are expected to enhance buyer confidence, particularly among health-conscious consumers and clean-label food brands.

Pussalla Agri Ventures emphasised that its organic cinnamon is sourced entirely from its own cultivated estates.

“This estate-to-exporter integration ensures full control over quality, traceability, and processing integrity. The company’s model allows cinnamon to be harvested, processed, and packed under continuously monitored conditions, maintaining strict alignment with international organic standards,” they noted.

Speaking further they said:

“Sri Lanka supplies the majority of the world’s True Ceylon Cinnamon, a spice prized for its delicate aroma, low coumarin levels, and reputed medicinal properties. The growing global demand for certified organic spices has created new opportunities for local producers who meet international compliance standards. Pussalla Agri Ventures’ certification achievement places it among a select group of Sri Lankan exporters adopting globally recognised organic systems, thereby enhancing the country’s reputation in high-value spice markets.”

“As organic food sales continue to rise in North America and Europe, certifications such as these are becoming essential rather than optional. For Pussalla Agri Ventures, the journey from conventional to certified organic is not merely a compliance exercise but a strategic repositioning aimed at long-term sustainability and premium pricing power.”
