Develop practical faceting skills with our gemstone faceting guides, covering rough selection, orientation, cut planning, preforming, cutting and polishing. Learn how factors such as crystal structure, cleavage, fracture, inclusions, colour zoning, pleochroism, usable yield and optical performance can influence decisions from the first examination of the rough to the finished gemstone.

How to Evaluate Sapphire Rough for Faceting: Orientation, Colour, Inclusions and Yield
Gemstone faceting combines gemmological knowledge, precision and craftsmanship. The properties of each piece of rough influence decisions long before the first facet is cut: crystal structure, cleavage and fracture, inclusions, colour zoning, pleochroism, transparency and the shape of the original rough can all affect orientation, design choice and potential yield. Understanding these characteristics helps the faceter balance weight retention with colour, brilliance and overall optical performance.
The Natural Gems Belgium faceting guides explore the complete process from evaluating and selecting natural gemstone rough to orientation, preforming, facet design, cutting and polishing. Individual guides also examine the different behaviour of gem materials such as quartz, corundum, garnet, beryl, peridot and other facetable minerals, including practical considerations when choosing laps, polishing methods and suitable cutting approaches.
Whether you are learning gemstone faceting for the first time or refining an established technique, these guides are intended to provide a technically informed reference for making better decisions at the faceting machine. As this section grows, it will combine general faceting principles with stone-specific guidance to help transform carefully selected rough material into well-proportioned finished gemstones.
