The Academic Standard for
Gemological Analysis.
We supply global gemological laboratories and grading academies with meticulously curated teaching specimens. From distinct color and clarity sets to synthetic detection practice parcels, our factory provides the raw data your students need to master the microscope.
The Educational Specimen Protocol
Grading Specimen Sets
Unlike our standard VVS-VS commercial parcels, we deliberately curate educational sets spanning a wide spectrum of characteristics. We supply stones with varying colors (D to K) and specific clarity features (crystals, feathers, twinning wisps) for students to practice microscopic plotting and grading.
#4C_Grading_KitsAuthenticity & Detection Training
Equipping the next generation of gemologists requires hands-on experience. We provide mixed “blind” test parcels featuring HPHT, CVD, and specific inclusions to train students in the critical task of distinguishing lab-grown melee from natural diamonds and identifying CZ simulants.
#Synthetic_DetectionCut Quality & Symmetry Studies
Students preparing for GIA or IGI exams must understand proportion and symmetry deviations. We offer study sets contrasting Ideal 57-facet cuts against stones with intentional symmetry faults, poor polish lines, or off-center culets for comparative visual analysis.
#Symmetry_AnalysisCalibration for Academic Study
Providing laboratories with access to all standard international sieve sizes, allowing instructors to build comprehensive size-chart reference kits for their students.
