Reference block for evaluating diamond fluorescence intensity: GIA Fluorescence Reference Block

GIA Fluorescence Reference Block is a calibrated tool for accurately determining the intensity of blue fluorescence in diamonds. This block was created based on data from millions of diamonds graded by laboratories GIA worldwide and provides a standard for visual evaluation of fluorescence.

Main advantages

1. Precise calibration: Uses the same reference standards as those used in GIA laboratories.
2. Four levels of fluorescence: the holes on the block correspond to the upper limits of the GIA grading – “None”, “Faint”, “Medium” and “Strong” fluorescence.
3. Easy recovery: The package includes 36 replacement fluorescent paper strips.
4. UV light compatibility: Ideal for use with long-wave UV lights with a wavelength of 365 nm

Use

• For professional gemologists when evaluating the intensity of blue fluorescence in diamonds.
• A great tool for teaching students in gemology or as part of gemological laboratories.
• Accurate on-site fluorescence comparison during diamond analysis or grading.

Technical specifications

• Block dimensions: 96mm x 26mm x 9mm.
• Weight: 43 g.
• Package contents: Calibrated reference block, 36 spare fluorescent paper strips.
• Material: High-quality construction ensuring long service life.

Benefits of evaluation

• It offers a reliable visual reference for fluorescence determination without the need for advanced instrumentation.
• Eliminates subjective errors in evaluation thanks to precisely calibrated visual scales.
• Easy to use in combination with UV light allows for fast and accurate results.
