About this app

Move away from relying solely on portable hardware lookups and pure mental memorization. Gem Scope is a professional gemological logbook and mineral reference companion engineered for gemologists, jewelers, and mineral collectors to input raw optical parameters, identify unknown specimens, and archive their private collections within a structured mobile terminal.

Core Features & Gemological Mechanics:
Multi-Parametric Identification Tool: Input precise physical properties observed on your refractometer directly into the app. Log explicit metrics across dedicated diagnostic modules including Refractive Index, Birefringence, and Specific Gravity, with quick-toggle options to switch seamlessly between single-value configurations and variable parameter ranges.

Ranked Differential Match System: Run input criteria against the system library to generate a differential list of prospective stones ranked by match probability. Review your active parameters at a glance via the Input Summary card and organize results instantly through targeted sorting filters: Match %, A-Z, and Best RI.

Extensive Mineral Reference Database: Access a foundational mineral index loaded with detailed optical characteristics. Sift through profiles using comprehensive built-in search filters to narrow down targets by Color, minimum or maximum refractive ranges (RI Min / RI Max), specific crystal systems (Cubic, Hexagonal, etc.), or clear structural categories (Natural vs. Synthetic).

Specimen Collection Ledger: Build an illustrated inventory vault under the My Collection workspace. Document your curated items under specific evaluation tabs (All, Unknown, Needs Testing) alongside detailed records tracking carat mass, physical dimensions, origin notes, and authenticity confirmations.

Diagnostic Session History: Revisit and review past diagnostic operations at any time via a dedicated History log tab to verify matching processes and ensure no technical findings are misplaced.

App Customization & Workspace Settings:
Flexible Display Preferences: Calibrate your testing environment to match your specific laboratory instruments. Toggle your primary dimension metrics between Metric and Imperial units, and customize your decimal configuration format (Dot vs. Comma).

Automated Interface Behaviors: Optimize your logging workflows by enabling helpful Show Input Hints for quick field navigation or activating Auto-save Sessions to secure your diagnostic data automatically.

Data Management Protocols: Maintain full authority over your proprietary collection records. Back up your inventory instantly via the Export Collection and History portal or completely wipe data configurations using the Clear All History action block.
