Diamond and Coloured stone Testing LIMS for Grading and Certification
Gem and Diamond LIMS Configured Around Grading and Certification Workflows
The sector in practice · Gemmology
Three views of your gemmology workflow
Lims.science generates analytical reports directly from validated results. In gemmology, these reports bring together the stone’s identity, the 4Cs, proportions and clarity characteristics in a versioned document.

Key Features Built for Diamond & Coloured stone Testing Labs
Control coloured stone intake, instrument assignments, grading checks, certificate review and authorised release in one gemmological LIMS.
Track Stones
Automate sample intake for diamonds and coloured stones, ensuring full chain of custody from arrival to final grading.
Customer-Configured Workflows
Set rules that move stones through grading stages automatically, saving time on colour, clarity, cut, carat, and advanced gemological testing.
Analytics and Metrology
Integrate spectrometers, microscopes, and other gemological equipment directly with no manual re-entry or formatting issues.
Quality Control
Calibration status, configured decision rules and independent grading checks support authorised review against applicable methods and criteria before release.
Generate Certificates
Produce certificates that follow your grading standards and any local disclosure rules.
Fully customisable
Adapt workflows, certificate templates, and reporting formats to match your lab’s exact processes for diamonds or coloured stones.
Connected Gemmological Laboratory Management, Powered by Odoo ERP
Lims.science runs entirely on Odoo, a powerful ERP system trusted by over 28 million users across the world.
We’ve adapted it specifically for diamond and coloured stone testing laboratories. You can manage everything from stone tracking and grading to compliance, certificate generation, inventory, and reporting in one place.
- Configure grading methods, quality parameters, and measurement units for diamonds and coloured stones
- Track stone intake, storage conditions, and analysis progress from initial inspection to final certification
- Approve or reject grading results with audit trails, including rechecks and method deviations
- Assign access by role so graders, QA officers, and clients only see the data they need
- Centralise multi-site operations such as different grading branches or international partner labs in one dashboard
- Access anytime with a cloud-based system or host it on your own servers

FAQs
How does this LIMS support international gemmological standards?
Yes. Lims.science supports gemmological laboratories seeking or maintaining ISO/IEC 17025 accreditation and can be configured around applicable CIBJO, GIA and IDC requirements. Features include secure chain of custody, reviewable grading logs and defined quality-control review steps for diamonds and coloured stones.
Can your system generate coloured stone certificates?
You can configure diamond and coloured stone certificates around the laboratory’s controlled format, branding and applicable classification or disclosure rules. QR-based verification can be included where enabled and validated for the intended use.
Can the gemology LIMS integrate with our gemological instruments?
Supported spectrometers, microscopes, imaging systems and other gem-testing instruments can connect through scoped interfaces that retain instrument identity, method binding and transfer status with each result.
Does the system support multi-location labs and multiple users?
Absolutely. Whether you manage one gem lab or a network of branches, the LIMS allows:
Role-based access for graders, QA officers, and clients
Centralised or location-specific data control
Standardised SOPs and workflows for grading and certification
It scales from boutique labs to international gem testing operations.
Can the LIMS handle both diamonds and coloured stones?
Yes. It supports workflows for diamonds, coloured stones such as rubies, sapphires, emeralds and other varieties. Each workflow can have its own grading criteria, parameters, and certificate templates.
What kind of support and training do you provide?
We offer remote onboarding sessions, step-by-step training for graders and administrators, and ongoing technical support. We also help configure workflows to match your exact processes.
