Traditional jewelry appraisals attempted the recognition of the origin of a gemstone based on criteria of its physical properties include, but not limited to color, refractive indices, and microstructure. However, these criteria, in addition to its inclusions, are generally failed to resolve the locality and origin of a gemstone without doubt. Through careful examination and compilation of Raman spectroscopic data, Argyle pink diamonds can be classified as two types according to their characteristic Raman spectra. The method of the present invention provides sound basis for the rapid determination of the authenticity of the Argyle pink diamonds by Raman spectroscopy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rapid identification method of Argyle diamond's origin by charactristic Raman spectra","description":"The origin of a gemstone often governs its value.
