How to calculate rough, raw, crude, uncut
diamond prices:
Determining prices of rough diamonds starts
by evaluation of rough diamonds.
This requires a specific gemological
knowledge as well as general expertise, structure analyzing about cutting during
sorting technics by:
Classification of rough jewelry diamonds and
industrial diamonds
Sorting by shape: octahedral, cubic, macle,
and dodecahedron crystals, determining their ultimate form in the
rough
Sorting by weight and size.
Sorting by color.
Sorting by distortions.
Sorting by clarity, structure and structural
defects: external and internal inclusions, cliveages, marks, naart, maccles...
Analyze to determine if a rough diamond is
to be cleaved, sawed or retained.
Analyze and detect of strain and stress
within the internal molecular structure by polariscope.
Sketching of rough diamonds pinpointing
impurities within the diamond.
