A lightweight, high-performance, and offline-first CLI tool designed specifically for lapidaries,
gem cutters, and mineral enthusiasts worldwide.
This program is free for everyone. It was created with a specific focus on the global lapidary community.
Many talented cutters operate in Asian countries or developing regions where high-end hardware,
stable internet, and modern software environments aren't always available.
To ensure maximum accessibility, this tool is:
-Written in DOS/Batch: Requires zero installation. No Python, no Java,
no complex environments. If you have a PC, it runs.
-Offline First: The entire mineral database is stored locally.
Internet is only required if you choose to use the optional Web Resources.
-Ultra-Lightweight: It takes up virtually no disk space and can run on even the oldest machines.
-Smart Search: Features an "Auto-Open" function. If your search (e.g., "Hac")
matches only one mineral (e.g., Hackmanite), it opens the data sheet immediately.
-Mineral Database: Currently includes 250 minerals, with plans for continuous expansion.
-Integrated Web Dashboard: A categorized hub for Prospection (maps), Faceting (designs),
Market Prices, and Technical Education.
-Technical Specifics: Each entry follows a rigorous template including chemical formulas,
hardness, refractive index, and cutting suggestions.
Each mineral in the database provides detailed technical specifications
essential for identifying and working with the stone:
-Chemical & Physical: Name, Formula, Crystal System, Hardness, and Specific Gravity.
-Optical Properties: Refractive Index, Birefringence, Optical, and Refraction type.
-Workability: Cleavage, Fracture, and suggested Cuts (Cabochon vs. Faceted).
-Geology: Primary Sources and known Phenomena or Treatments.
You can download the version 1.0 here:
Note: The .exe version is a standalone file with the database already embedded.
For .EXE users: Simply download and run the executable.
For .BAT (Source) users:
-
Download the repository.
-
Important: Ensure the data folder is in the same directory as the .bat file.
-
Run GEMSTONE_DATABASE.bat.
We are committed to growing this tool for the global community. Our future goals include:
[ ] Expansion to 500+ mineral files.
[ ] Integrated Hydrostatic Scale Calculator for Specific Gravity.
[ ] Carat-to-Gram and Weight estimation converters.
[ ] ASCII visualization of Crystal Symmetry systems.
v1.0 (Current): Launch with a database list of 250 minerals. Includes Smart Search (Auto-Open logic),
expanded Web Dashboard (Instrumentation & Software), and improved input normalization for spaces and hyphens.
