Pearl Spectral and Compositional Data for Optical Properties Study

Spectral, color, and compositional data for five pearl types—ordinary freshwater, 'Edison', Akoya, golden, and black pearls. The dataset was created by Fukang Liu and last updated on 2026-04-18. It is a 1.3 MB Excel file containing measurements from multiple analytical techniques.

Use Cases

• Classifying pearl types based on spectral signatures described in the study
• Modeling the relationship between pearl composition and optical properties like color
• Developing spectral analysis methods for gemstone authentication based on the described techniques

Strengths

• Data from multiple analytical techniques (UV-Vis, Raman, EDXRF, IR) is likely integrated.
• Focuses on five distinct pearl types for comparative analysis.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is medium detail; specific measurement ranges and protocols require inspection of the file.
