The completion time from 60 minutes.
The result is a definition:
- Size-weight indices insert (raskreplennye inserts and inserts in the product)
- Insertion of material (including mineral species or varieties)
- The nature of the origin material paste (natural, synthetic, artificial)
- Identify the presence of gentrification, its type and degree of impact on insert
- Qualitative characteristics (for standards HUNDRED MHZ 2016 and the international ISO standards)
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.
