Key Features Built for Diamond & Gemstone Testing Labs

Control gemstone intake, instrument assignments, grading checks, certificate review and authorised release in one gemmological LIMS.

Track Stones

Automate sample intake for diamonds and precious or semi-precious gemstones, 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 gemstones.

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 gemstones.

Can your system generate gemstone certificates?

You can configure diamond and gemstone 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 gemstones?

Yes. It supports workflows for diamonds, precious gemstones like rubies, sapphires, and emeralds, as well as semi-precious stones. 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.
