Advanced examination

The completion time  of 3 working days.
The result is a definition:
  1. Size-weight indices and the material insert (raskreplennye inserts and inserts in the product)
  2. The nature of the origin insertion (natural, synthetic, artificial)
  3. Detecting the presence of gentrification, its type and extent
  4. qualitative characteristics (for standards HUNDRED MGC 2016 and the international ISO standards)
  5. area of origin of the natural material inserts
  6. additional individual characteristics jewelry inserts

EQUIPMENT AND METHODS

  • Loupe, Gemological lamp – visual inspection, prior sensory information about the insert;
  • Analytical laboratory scales – weighing expertise with an accuracy to hundredths of a gram/carat;
  • Micromemo device – determination of linear dimensions of the object of examination with an accuracy of hundredths of a millimeter (for loose inserts), or to a tenth of a millimeter (for fixed inserts);
  • The polariscope – definition optical nature of the material of the insert;
  • Refractometer – determination of refractive index of the material of the insert;
  • Time domain reflectometer – definition of the average value of the refractive index of the material of the insert (if necessary);
  • Microskop – determination of the nature of polychroism material inserts;
  • Thermomaster – defining the relative rate of thermal conductivity of the material of the insert;
  • Gemological UV lamp – defining parameters of a luminescence of the material inserts in ultraviolet rays;
  • Specialized testers luminescent properties – define additional parameters on the luminescence properties of the material of the insert;
  • Microscope – study of internal inclusions and inhomogeneities in the material of the insert (including polarized light and immersion in liquids); the use of arbitration as a means for defining quality characteristics of the inserts on the parameter "purity";
  • Instructional and methodological documentation – a set of reference books, methodical and guidance documents;
  • Sets standards color – definition of quality characteristics of the inserts on the parameter "color";
  • Proportionsof – determination of dimensional and angular parameters and evaluation of quality characteristics of cut panels on the parameter "cut proportions";
  • A set of diagnostic spectral equipment – determining the material of the insert, the confirmation of the natural origin of the material of the insert, the confirmation of the finishing material inserts
  • Analytical spectral devices – determination of the individual spectral and physico-chemical characteristics of the material of the insert.
