Sri Lankan gemological scientist innovates ‘one of world’s most powerful’ gem analysis microscopes
A Sri Lankan gemological scientist has unveiled a high-magnification digital microscope designed to enhance analysis speed and reveal internal features far beyond the reach of conventional dimensions. The innovator believes this innovation could strengthen transparency throughout the country’s gem and jewellery industry. Milinda Edirisinghe, founder of the Gemological Report of Ceylon (GRC) laboratory in Colombo, said the microscope is the result of two years of research and development to overcome the optical limitations of conventional gemological microscopes.
According to Edirisinghe, the new system consists of four digital microscope models capable of magnifications of 450x, 600x, 1000x, and 1440x, allowing gemologists to examine microscopic internal features, or inclusions, with substantially greater clarity than conventional laboratory equipment. These models are named by Edirisinghe as the Don Berry 450x, Don Berry 600x, Don Berry 3rd Eye 1000x, and Don Berry 3rd Eye 1440x.
“The biggest limitation in gemology has always been what the microscope could actually reveal,” Edirisinghe said in an interview. “Simply increasing magnification was not enough. Many internal features remained difficult to observe clearly, forcing laboratories to rely on indirect analytical techniques and expert interpretation.”
He further stated that these advanced microscopes will reveal many previously undiscovered aspects of gemology to the world. Gemological laboratories routinely use advanced analytical methods such as Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy and other spectroscopic techniques to identify gemstones, determine treatments and analyse internal characteristics that cannot easily be resolved through optical examination alone. Edirisinghe said this innovation enables much clearer visual observation of inclusions, crystal structures and other internal characteristics.
One of the other significant benefits, he said, is the ability to dramatically reduce examination time, as the system’s ultra-high magnification and exceptionally clear images allow gemologists to swiftly analyze stones and identify internal inclusions.
“Microscopic examination of a single gemstone could previously take anywhere from 2-3 minutes to few hours, often hampered by poor vision and forcing us to guess the inclusion type most of the time,” he said. “With the new system, a complete examination can often be completed in less than a minute.”
The microscope incorporates high-resolution digital imaging, allowing photographs and video recordings of internal gemstone features to be captured, archived and incorporated into laboratory reports. Edirisinghe said the digital records also improve traceability and provide permanent documentation for future references. The system is also designed to integrate artificial intelligence-assisted image analysis. It captures exceptionally clear, ultra-high-quality images of inclusion structures, which are fed into the AI system to be precisely tallied and matched with existing images. According to Edirisinghe, the AI software compares these captured inclusion patterns with an expanding database of reference images to assist gemologists in identifying mineral inclusions and geological characteristics associated with particular gemstone types and origins.
Edirisinghe believes the technology could have implications beyond laboratory testing. More detailed identification of internal features may enable jewellery manufacturers to classify gemstones with greater confidence, improve quality assurance and adopt more transparent pricing strategies for premium jewellery, he said. He also says that improved documentation could increase consumer confidence by providing more comprehensive certification of high-value gemstones and diamonds.
According to Edirisinghe, most gemological laboratories in Sri Lanka currently use microscopes offering optical magnification ranging from around 90x to 180x, although microscope configurations and capabilities vary between laboratories. His new system combines optical and digital technologies to achieve higher effective magnification while simultaneously capturing digital images.
As a veteran gemological scientist with over two decades of experience in gemstone mining, trading and geological research, Edirisinghe said he developed the microscope using specially imported Japanese optical components after numerous prototype modifications. He has also collaborated with gemological laboratories in Thailand during his research.
He said the newly established GRC laboratory aims to raise the standard of gem certification in Sri Lanka by combining advanced microscopy, digital documentation and AI-supported analysis to produce more detailed laboratory reports.
Edirisinghe invites gemologists, jewellers, exporters and researchers to evaluate the technology through live demonstrations, saying independent assessment by industry professionals will ultimately determine its value to the sector.

NSB Group delivers Rs.22.5bn operating profit in 1H 2026 as lending and core income strengthen
National Savings Bank Group (NSB) recorded resilient core banking performance during the first six months of 2026, supported by stronger net interest income, a notable expansion in fee-based earnings and continued growth in loans and advances. The results demonstrate the Bank’s capacity to maintain business momentum while navigating cost pressures and volatility in market-related income.
The Bank reported total operating income of Rs. 45.8 billion for the period, an increase of 3.1% compared with Rs. 44.5 billion in the corresponding period of 2025. Net operating income increased by 2.3% to Rs. 49.1 billion from Rs. 48 billion reported a year ago, providing a stable foundation for the Bank’s operations and customer-focused growth agenda.
Net interest income rose by 5.5% year-on-year to Rs. 44.2 billion, compared with Rs. 41.9 billion in the first half of 2025. This improvement was supported by a 4.7% reduction in interest expenses to Rs. 54.5 billion, despite a marginal moderation in interest income to Rs. 98.6 billion. The result reflects disciplined balance-sheet management and the Bank’s continued focus on maintaining a sustainable funding and asset mix.
The Bank also achieved substantial growth in fee-based earnings. Net fee and commission income increased by 37.0% to Rs. 1.40 billion, from Rs. 1.02 billion a year earlier. The increase underlines the growing contribution from transaction-led services and the Bank’s ongoing efforts to broaden non-interest revenue through customer-centric and digitally enabled banking solutions.
Profit before Tax (PBT) amounted to Rs. 22.6 billion, compared with Rs. 24.1 billion in the first half of 2025, while profit after tax stood at Rs. 13.4 billion, compared with Rs. 14.7 billion. The moderation in profitability principally reflected higher operating costs and the lower contribution from trading and derecognition gains. Personnel expenses increased to Rs. 13.8 billion from Rs. 11.5 billion, while other operating expenses rose to Rs. 4.3 billion from Rs. 4.1 billion.
Despite these pressures, the Bank preserved a substantial earnings base and continued to invest in the people, systems and service capabilities required to improve operational resilience and the customer experience. Income tax for the period amounted to Rs. 9.14 billion, while VAT and the Social Security Contribution Levy on financial services together exceeded Rs. 7.29 billion. In addition, the Bank declared a dividend of Rs. 7.4 billion to the Government as its sole shareholder. Accordingly, NSB’s total contribution to the Government through dividends, taxes and levies amounted to Rs. 23.8 billion, underscoring the Bank’s significant contribution to public finances and national development.
Commenting on the results, National Savings Bank Chairman Dr. Harsha Cabral PC said: “The first-half results reflect the resilience of NSB’s core business model and the enduring confidence placed in the Bank by generations of Sri Lankans. Our priority remains the prudent stewardship of public savings while supporting productive economic activity, financial inclusion and sustainable national development.”
NSB’s total assets increased by 2.1% during the first six months of the year to Rs. 1.87 trillion, from Rs. 1.83 trillion at end-December 2025. Loans and advances recorded a strong 9.1% expansion to Rs. 601.01 billion from Rs. 550.83 billion, demonstrating the Bank’s continued support for the financing needs of individuals, households and eligible institutional customers within its mandate.
Deposits, the principal source of funding for NSB, increased by 1.5% to Rs. 1.63 trillion from Rs. 1.61 trillion. The sustained growth in the deposit base reflects continued public confidence in the Bank and provides a stable platform for its savings-led business model. The Bank’s financial position remained sound, with total shareholders’ equity increasing by 4.1% to Rs. 123.91 billion from Rs. 119.05 billion. Retained earnings rose by 12.4% to Rs. 52.34 billion, further strengthening the Bank’s capacity to support future growth and absorb potential shocks.
Acting General Manager/CEO of National Savings Bank, Mr. Rohana Bandara Weerakoon, said: “Our focus is on translating the Bank’s trusted savings franchise into sustainable customer value. The growth achieved in lending, fee income and shareholder’s equity is encouraging. We will continue to strengthen digital access, service quality, cost discipline and risk management while delivering on NSB’s national mandate.”
The Bank’s profitability indicators continued to reflect the strength of its core banking activities, although higher operating expenses moderated overall returns. The net interest margin improved to 4.81% from 4.74% at the end of 2025, demonstrating an improvement in the Bank’s core interest spread. Return on assets before tax remained broadly stable at 2.46%, compared with 2.48%, while return on equity stood at 22.30%, compared with 25.08% at the end of 2025.
Asset quality improved during the first half of 2026. The net Stage 3 loans ratio declined to 2.05% from 2.52% at the end of 2025, indicating a reduction in net impaired credit exposures relative to the loan portfolio. At the same time, the Stage 3 impairment coverage ratio strengthened to 59.77% from 58.54%, reflecting improved impairment coverage against Stage 3 loans.
NSB maintained capital buffers comfortably above the applicable regulatory minimum requirements. The Tier 1 capital ratio stood at 19.72%, compared with the regulatory minimum of 8.5%, while the total capital ratio stood at 21.1%, well above the minimum requirement of 12.5%. These ratios demonstrate the Bank’s capacity to absorb potential risks while supporting continued business growth.
The Bank also maintained a strong liquidity and stable funding position. The all-currency liquidity coverage ratio stood at 311.88%, substantially above the statutory minimum of 100%, reflecting the availability of sufficient high-quality liquid assets to meet short-term liquidity requirements. The net stable funding ratio stood at 196.17%, also comfortably above the regulatory minimum of 100%, demonstrating the stability of the Bank’s longer-term funding profile.
