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

Sri Lanka pitches Saudi investors for new investment partnerships
By Ifham Nizam
Sri Lanka is pitching Saudi Arabia for greater investment and deeper trade ties, seeking to attract Saudi capital into new development opportunities while aligning bilateral economic cooperation with the Kingdom’s ambitious Vision 2030 agenda, Ports and Civil Aviation Minister Anura Karunathilaka, chief guest at Saudi Arabia’s 96th National Day celebrations in Colombo, said.
Addressing the National Day reception at ITC Ratnadipa, Karunathilaka said Sri Lanka was keen to identify new areas of economic cooperation with the Kingdom and create fresh opportunities for Saudi investors and businesses.
‘We look forward to creating new opportunities for the people of both countries by working in cooperation with Saudi Arabia’s Vision 2030 and its broader development initiatives, he said.
The minister said Sri Lanka wanted to move beyond its existing development cooperation with Saudi Arabia and build a broader economic partnership encompassing investment, trade and new development projects.
He noted that Saudi Arabia had already made a substantial contribution to Sri Lanka’s development. Since 1981, the Kingdom has provided concessional financing amounting to around Saudi Riyals 1.5 billion for 13 projects in Sri Lanka, supporting key sectors including energy, healthcare, education, drinking water and infrastructure.
Karunathilaka said Sri Lanka appreciated this support and was keen to build on the foundation created by those projects by opening further avenues for Saudi investment.
The minister’s investment pitch comes as Saudi Arabia advances its Vision 2030 programme, with the Kingdom seeking to diversify its economy and develop new international partnerships. Sri Lanka, meanwhile, is seeking to attract investment and expand economic opportunities through closer engagement with international partners.
Karunathilaka also highlighted the strong people-to-people links between the two countries, noting that nearly 250,000 Sri Lankans currently work and reside in Saudi Arabia.
‘They serve as an important bridge between our two countries and contribute significantly to strengthening the people-to-people ties between Sri Lanka and Saudi Arabia, he said.
He expressed appreciation for Saudi Arabia’s continued assistance to Sri Lanka and thanked the Saudi government for the facilities extended to Sri Lankan Muslims undertaking Hajj and Umrah pilgrimages.
Karunathilaka said Sri Lanka looked forward to working more closely with Saudi Arabia to strengthen political relations, broaden investment opportunities and enhance development cooperation.
Yaser Abdulrahman Al-Hazme, Chargé d’Affaires of the Royal Embassy of Saudi Arabia to Sri Lanka, said the embassy remained committed to strengthening bilateral relations by promoting political, economic and cultural communication between the two countries.
‘The embassy of the Kingdom of Saudi Arabia in Colombo has been keen during the past period to strengthen bilateral relations between the two countries by playing its role in supporting political, economic, and cultural communication, Al-Hazme said.
Al-Hazme also highlighted the embassy’s role in strengthening communication between Saudi and Sri Lankan institutions and following up on the interests of Saudi citizens in Sri Lanka.
‘On this precious national occasion, I extend my sincere thanks and appreciation to the government and people of the Democratic Socialist Republic of Sri Lanka for the attention and care given to relations between our two countries, and for the constructive cooperation that has contributed to strengthening the bonds of friendship and partnership between the Kingdom and Sri Lanka, he said.

Beyond the crisis: Sectoral paths to durable growth
Institute of Policy Studies of Sri Lanka (IPS)
Continued From last Friday
Regional infrastructure improvements beyond the Western Province are essential to close market-access gaps and improve efficiency. The Western Province alone generates 42% of Sri Lanka’s GDP, but the dynamics of such agglomeration may also be highly underestimated. Officially, barely a fifth is deemed ‘urban’ in the province, but IPS re-estimates from the 2024 census using population density and infrastructure access, place the true figure at nearly 61%. The absence of strong secondary cities and industrial clusters outside the province reduces the potential gains from this agglomeration, thereby weakening incentives for firms to locate elsewhere or decentralise operations.
Fiscal incentives can promote decentralised corporate operations by offering tax rebates, lower property taxes, and land access in secondary cities like Kalutara and Gampaha, leveraging the connectivity of Southern and Colombo-Katunayake Expressways. The Hambantota seaport and airport, along with Koggala and Mirijjawela Export Processing Zones, can help develop the Southern Province through geography-based tax concessions.
Immediate measures, such as pricing vehicle entry into Colombo city will support regional agglomeration while tackling the acute problem of city congestion. Adopting a low-cost, technology-anchored free-flow method, similar to the Automated Number Plate Recognition (ANPR) currently used in commercial parking facilities for vehicles entering the city, is one such means. Installing high-mounted overhead ANPR gantries at key arterial entry points can operationalise congestion pricing without disrupting traffic speed. Fee collection can use a system like E-Tags electronic toll collection on expressways, integrated with digital payment gateways like GovPay and LankaQR for dynamic, time-of-day variable pricing.
The renewable energy transition is vital to drive competitiveness, external shock resilience, and green growth. Sri Lanka’s transition to renewable energy (RE) has advanced from a mere aspiration to tangible progress. Yet, the evidence suggests the transition is advancing faster on the generation side than the system built to absorb it. Transmission capacity, market design, financing channels, and digital infrastructure have not kept pace with capacity additions, and this gap is what will determine the pace of the transition through 2030.
Capital spending on transmission must be ring-fenced by legally, operationally, and financially separating the electricity grid (the transmission network) from the rest of the energy sector or by the broader government budget as a protected public investment within the medium-term budget framework. Funding should shift from general budget support to dedicated multilateral facilities, reinforced by sovereign guarantees for eligible borrowing. To safeguard public funds, this must be paired with a clear tariff pass-through mechanism that effectively limits open-ended Treasury exposure.
To build market trust, domestic budget funding should be earmarked for market-design technical assistance, signalling strong policy ownership rather than relying on external donors. Transparency too should be strengthened by publishing a firm implementation timeline in the Budget statement and fully disclosing long-term fiscal commitments from Power Purchase Agreements, capacity arrangements, and ancillary services.
