Quality Without
Compromise.
Our quality management system ensures every analytical result is traceable, reproducible, and defensible — meeting the highest international standards for testing laboratories.
Systematic Assurance.
Our Quality Management System (QMS) is built around the ISO/IEC 17025 framework — the international standard for testing and calibration laboratories. Every process, from sample intake to report issuance, is documented and subject to regular review.
This systematic approach ensures that our analytical conclusions are not just accurate, but fully traceable and defensible — a critical requirement for clients who depend on our results for high-value commercial decisions.
Instrument Calibration
Regular calibration schedules using certified reference materials. Every measurement traces back to an established standard.
Internal Audits
Periodic internal audits review all aspects of laboratory operations — from analytical procedures to documentation practices.
Data Integrity
Digital chain-of-custody protocols ensure all raw data, spectra, and observations are permanently archived and tamper-evident.
Continuous Improvement
Corrective action procedures, management reviews, and method validation updates drive ongoing process refinement.
End-to-End Quality Control.
Sample Receipt & Registration
Unique identification, weight verification, photographic documentation. Chain-of-custody begins at intake.
Analytical Protocol Selection
Appropriate testing sequence determined based on material type, client requirements, and preliminary assessment.
Instrument Verification
Calibration checks on all instruments before each testing session. Reference standards scanned to confirm accuracy.
Multi-Instrument Analysis
Systematic data acquisition across Raman, FTIR, UV-Vis-NIR, EDXRF, and microscopy. All raw data archived permanently.
Expert Review & Interpretation
Senior gemmologist review of all data, cross-referenced with reference databases and ML-assisted pattern analysis.
Quality Check & Report Issuance
Secondary review, report formatting, digital certification, and micro-tag assignment before client delivery.
Our Quality Commitments.
Impartiality & Independence
G-ID Labs maintains complete independence from the gem trade. Our ownership structure, staff policies, and operational procedures are designed to prevent any commercial pressure from influencing analytical conclusions. All staff members are bound by confidentiality and conflict-of-interest policies.
Confidentiality & Data Protection
All client submissions, testing data, and report contents are treated as strictly confidential. Analytical data is stored in encrypted digital archives. Client information is never disclosed without explicit authorisation, and all staff undergo data protection training.
Competence & Training
All analytical staff hold recognised gemmological qualifications and undergo regular competency assessments. Continuous professional development includes conference attendance, peer-reviewed literature review, and participation in inter-laboratory comparison programmes.
Measurement Uncertainty
We maintain documented procedures for estimating measurement uncertainty across all quantitative analytical methods. Uncertainty budgets are evaluated for each instrument and method, ensuring clients understand the precision limits of our reported values.
Complaints & Appeals
A formal complaints and appeals procedure ensures that any client concerns are documented, investigated, and resolved objectively. Root cause analysis and corrective actions are implemented where applicable, with outcomes communicated to the complainant.
Quality You Can Trust.
Our commitment to quality is not a policy — it is the operational culture that defines every aspect of our laboratory.
