How to use it
- Select the correct laser wavelength for the gem and diagnostic question
- Focus on a clean, safe area of the stone or inclusion
- Collect Raman spectra for material identification or photoluminescence spectra for color centers
- Use low power first to avoid heating sensitive, filled, or organic materials
- Compare peak positions and luminescence features with trusted reference data
- Combine results with microscopy, FTIR, and chemistry when treatment disclosure matters
