Cut the secondary pavilion facets. You must stop cutting the exact moment the edges of these new facets touch the intersection of the primary facets and the girdle. Phase 3: Transferring the Stone
Facet angles are calculated using the specific refractive index (RI) of the gemstone material. This prevents light leakage and maximizes total internal reflection.
Meetpoint faceting is a technique where each facet is cut and polished to meet precisely at a designated point on the stone, as opposed to "eyeballing" or cutting by consistent surface area. This method relies on the use of a (specifically a facet head with a digital or mechanical angle gauge) to cut specific angles and index positions. Why Choose Meetpoint Faceting?

is a foundational instructional guide for gem cutters focusing on the meetpoint technique, which ensures all facets intersect precisely at designated points. This article provides a comprehensive overview of the book's core concepts, the evolution of faceting techniques, and practical advice for sourcing educational materials legally. What is Meetpoint Faceting? Cut the secondary pavilion facets
Faceting is the process of cutting a gemstone into a specific shape with flat surfaces, called facets, that refract light in a way that enhances the gem's beauty. The meetpoint is a critical aspect of faceting, referring to the precise point where two facets intersect. Proper alignment and precision at the meetpoint are essential for achieving optimal brilliance and fire in the finished gemstone.
Mastering meetpoint faceting requires an understanding of several core principles:
: Facets mirror each other precisely across the stone. This prevents light leakage and maximizes total internal
The "Introduction to Meetpoint Faceting" could be a guide or tutorial designed for individuals interested in learning about faceting, specifically focusing on meetpoints—perhaps how different planes or surfaces intersect or meet in the process of faceting stones or in geometric studies.
: The faceting machine’s height and angle are locked in based on a specific diagram. Key Steps in the Meetpoint Process
Using the established girdle as your baseline, you cut the crown facets. Each row of facets is cut down until it perfectly touches the corners of the girdle or the corners of the adjacent crown facets. Step 6: The Table
