Problem addressed
  • Traditional gemstone inspection relies on gemstone testing laboratories.
  • Most of the existing tools for testing are bulky and expensive, and not cost-effective for jewellery vendors to set up in the retail shops.
  • The inspection process usually takes at least a week to  complete.
  • Service charges and labour costs are high.
Innovation
  • A compact fluorescence analyser is developed to measure the spectrum of the gemstones to differentiate the types of gemstones.
  • 3D images in high resolution are captured, and point-cloud analysis is used to inspect the surface profiles with 1mm spatial accuracy.
  • Synthetic and simulated diamonds can be differentiated.
  • Support wireless connection to view the image on smartphone.
  • Highly portable handheld box which saves space and is easy to carry.
  • Built-in database allows direct comparison and instant authentication.
  • Simple operations; single click to verify the gemstones while updating the database in parallel.
Key impact
  • A cost-effective way to analyse and identify gemstones with one click.
  • Short inspection time; supports samples of all sizes.
  • Non-contact procedures safeguard the completeness of jewellery.
  • Compact and handy design enabling simple installation.
Application
  • Smart jewellery inspection
  • Antique authenticity inspection
  • Quality check for manufacturing
