Gem Cut Calc

Bring mathematical precision directly to your lapidary bench. Gem Cut Calc is a streamlined geometric utility designed for gem cutters and hobbyists to instantly evaluate stone proportions, cutting facets, and dimension relationships. Cleanly calculate vital physical profiles before making your first facet cuts.

Core Features & Mechanics:
Targeted Faceting Modules: Work efficiently with a multi-tab interface tailored for individual stone dimensions, featuring dedicated calculation panels for Depth, Table, Crown, and Pavilion parameters.

Proportional Depth Calculations: Determine total depth values seamlessly. Input the stone's overall Diameter (mm) and target Depth % to instantly generate critical outputs, including Total Depth, Depth Ratio, and Half Depth.

Table Width Analysis: Calculate precise table widths by cross-referencing your stone's base diameter against your intended table percentage parameters.

Pavilion Precision: Compute exact pavilion depth values by inputting the targeted Pavilion Angle (°) alongside baseline stone dimensions.

Save & Build Your Library: Keep a permanent record of successful cutting scenarios. Use the Save Result toggle to store your favorite bench setups, allowing you to quickly compare distinct geometric plans side by side.

History & Bench Preferences:
Custom Decimal Precision: Fine-tune the rounding accuracy of your numerical outputs (such as configuring results to 2 decimal places) to match your precise faceting machine calibration.

Centralized Storage Controls: Keep your history clean and manageable. Access the settings panel to clear calculation logs or remove archived setups instantly with dedicated commands like Clear All History and Remove All Favorites.
