Certification
Natural Diamond Certification
Scientific verification and grading for natural diamonds — loose or studded.
Diamond Grading Report
A complete, independent assessment of a loose natural diamond. Captures the 4Cs, proportions, measurements, fluorescence, and identifying features. High-resolution imaging and QR-based digital verification ensure full authenticity and transparency.
Studded Jewellery Analysis
A mounted-jewellery report for pieces set with natural diamonds. Includes total natural diamond weight, colour & clarity range (visible in setting), metal details, and natural-origin screening to eliminate undisclosed lab-growns.
Uncut Diamond Jewellery Report
For jewellery set with rough/uncut natural diamonds. Analyzes crystal features, transparency, and morphology, with weight and size estimations in mounted condition.
Screening Report
The IDT Screening Report confirms whether a loose diamond or a diamond in jewellery is a Natural Diamond. Using advanced detection and spectroscopic tools, the report verifies origin without offering full grading. It includes basic details such as shape and estimated weight (for mounted pieces) along with a clear confirmation of natural identity. This certificate is ideal for quick, reliable origin assurance for both trade and retail.
Lab Grown Certification
Complete disclosure and grading for diamonds grown via HPHT or CVD.
Lab Grown Grading Report
A full 4C grading report for loose lab-growns. Confirms synthetic origin using spectroscopy, photoluminescence, and growth-structure analysis. Fully discloses any post-growth treatments.
Lab Grown Studded Jewellery Report
Evaluates jewellery set with lab-grown diamonds. Includes origin confirmation for each visible stone, colour & clarity range, weight estimation, and disclosure of treatments.
Lab Grown Uncut Studded Jewellery Report
For jewellery set with rough/uncut lab-growns. Documents growth morphology, strain patterns, surface indicators, and size/weight estimates.
Gemstone Certification
Scientific identification and analysis of coloured gemstones — natural, lab-grown, or mounted.
Natural Gem Testing Report
Identifies species and variety using refractive index, specific gravity, spectroscopy, inclusion analysis, pleochroism, and fluorescence. Records treatments and origin indicators where measurable
Lab Grown Gem Testing Report
Confirms synthetic origin through growth structures, spectroscopic signatures, and diagnostic inclusions.
Studded Gem Testing Report
For jewellery containing gemstones (mounted). Uses non-invasive techniques to determine identity, treatments, and weight estimations.
Assortment Services
Professional sorting of diamonds by size, colour, clarity, cut, fluorescence, and shape. Ensures uniformity and consistency for manufacturers, wholesalers, and retailers handling high-volume production.
Laser Inscriptions
Precise, permanent, microscopic markings on diamond girdles — certificate numbers, branding, or personalised codes. Enhances traceability without affecting weight or clarity.
Security Seals
Tamper-evident, uniquely coded packaging for loose diamonds and gemstones. Links seamlessly to certificate data and maintains chain-of-custody integrity during display, transport, and sale.
Screening Service
High-throughput detection of undisclosed lab-growns, simulants, and treated stones in loose diamonds, melee parcels, and mounted jewellery. Ensures regulatory compliance and supply-chain transparency.
Mobile Laboratory
IDT’s Mobile Laboratory brings advanced gem testing — for diamonds, lab-growns, gemstones, and jewellery — directly to your premises. Equipped with state-of-the-art instruments and managed by trained gemologists, it delivers secure, on-site analysis with fast turnaround and zero logistics risk.
