Gem Measure overlays an adjustable polygon onto a gemstone image or video feed and instantly calculates edge length deviations, symmetry, and overall quality. It's designed for jewelers, gemologists, and hobbyists who need quick, accurate measurements without expensive software.
Works with USB microscopes, webcams, or any image file.
How to Use
Open an image (F) or connect a camera (C).
Adjust the polygon by dragging its vertices to match the gem outline.
Read deviation percentages, symmetry score, and edge lengths directly on screen.
Calibrate (K) by clicking two points and entering their real distance (e.g., 5 mm) to switch to metric units.
Add rulers (M) to measure arbitrary lengths, dividing them into any number of equal parts.
Save results (S) or export a text report (E).
