Rock, Mineral & Gem Collection Management Software
Offline, secure, and on all of your devices with geological terminology.
Catalog your geological specimens with specialized rock and mineral collection software designed for serious rockhounds. From common minerals to rare specimens, fossils to polished gems, NM Collector helps you document your geological finds with proper scientific terminology.
Comprehensive Geological Tracking:
-
Scientific and common name classification
-
Crystal form and system documentation
-
Mohs hardness scale rating
-
Specific gravity measurements
-
Streak, luster, and color characteristics
-
Cleavage and fracture patterns
-
Location found and geological context
-
Estimated age and dating method
-
Weight and size measurements
-
Transparency classification
Perfect for amateur rockhounds, serious collectors, or educators building
teaching collections. Document your specimens with the scientific detail
they deserve—all stored securely offline on your devices.
The default coin geologic template is optimized for many collections with field names and dropdowns for most rocks and minerals. You can add and remove values to customize to your unique collecting needs. Please see our Features page for fields by tab available to all collections. Below are fields unique to this template.
Why Geological Collectors Choose NM Collector:
Scientific and Collecting Data Together
Track both scientific characteristics (Mohs hardness, crystal system, chemical formula, classification) and collecting information (locality, date collected, collection circumstances) in one integrated record. Unlike field notebooks or spreadsheets, NM Collector keeps scientific data, photographs, and provenance information organized and searchable.
​
Locality Documentation and Privacy
Proper locality data is essential for scientific specimens but may need to remain private for active collecting sites. NM Collector stores all locality information locally on your devices—no cloud upload means your collecting sites, landowner information, and access details remain confidential. This is critical for collectors who work with private landowners or mine owners.
Field Work and Lab Documentation
Use NM Collector in the field on mobile devices (completely offline), then expand documentation at home on desktop. Photograph specimens in situ, record GPS coordinates, note field observations, and make preliminary identifications during field work. Add detailed measurements, physical properties, and refined identifications when you return to your lab or home.
Multiple Specimen Types in One System
Whether you collect minerals, rocks, fossils, meteorites, or all of the above, NM Collector handles everything in one software package. Create separate collections by type or combine everything with filtering and search. Track micromounts, thumbnails, miniatures, cabinet specimens, and large display pieces with equal ease.
​
High-Resolution Photography for Tiny Specimens
Micromount collectors need detailed photographs showing crystal structure and diagnostic features. NM Collector accepts unlimited high-resolution photos per specimen. Capture images at multiple magnifications, document crystal faces, show fluorescence under UV, and maintain a complete photographic record.
​
Reference Collection Management
Many geological collectors maintain both systematic collections (organized by classification, locality, or type collection) and reference collections. Use NM Collector's flexible organization to manage both: filter by classification for systematic arrangement, search by locality for field area references, or create custom categories for teaching collections.
​
Multi-Collection Capability
Serious earth science collectors often have related interests: lapidary work, gemstones, crystal specimens, or cave formations. Use NM Collector for all of them without paying separate software subscriptions. Create unlimited custom collections, share data across collections, and manage your entire collecting hobby in one system.
​
No Subscription Required
Try full features free for 30 days, then choose a lifetime activation or use the free version. Your geological data remains accessible whether you pay ongoing fees or not. No locked features, no lost access to field data, no recurring costs unless you choose them.
FAQ - Geological Template
Q: What geological information can NM Collector track? A: The geological template includes fields for Mineral/Rock Type, Classification (igneous, sedimentary, metamorphic for rocks; silicate, oxide, sulfide, etc. for minerals), Hardness (Mohs scale), Specific Gravity, Color, Streak, Luster, Crystal System, and Chemical Formula. You can track both scientific data and collection provenance in one comprehensive system.
​
Q: Can I manage rocks, minerals, and fossils in the same software? A: Yes. Create separate collections for minerals, rocks, fossils, and meteorites, or combine everything in one comprehensive geological collection. The template is flexible enough to handle different specimen types with appropriate documentation fields. Use custom fields to add specimen-specific data like fossil period, formation names, or meteorite classification.
Q: How do I document locality information? A: The geological template includes Location/Storage fields that can be adapted for locality documentation. Record specific collection sites, formations, mines, or geographic coordinates. Use the Description tab for detailed locality information including access conditions, permission requirements, or historical significance of the collecting location.
​
Q: Can I track Mohs hardness and other physical properties? A: Absolutely. The template includes a Hardness field specifically for Mohs scale ratings. Use custom fields or the Description tab for other physical properties: specific gravity, fluorescence, streak color, cleavage, fracture type, or any other characteristics you want to document. The software is flexible enough to track whatever data matters to your collecting focus.
​
Q: Is my specimen collection data private and secure? A: Yes. NM Collector stores everything locally with no cloud upload. This is particularly important if your collection includes data about specific collecting localities (especially on private land or restricted areas). Your locality information, specimen values, and collection inventory remain completely under your control.
Q: Can I use NM Collector in the field while collecting? A: Definitely. NM Collector works 100% offline on iOS and Android devices. Take your phone or tablet into the field, photograph specimens in situ if desired, record GPS coordinates, document locality information, and add preliminary identifications on the spot—all without cellular service. Update identification and technical details when you return home.
​
Q: How do I handle specimens with uncertain identification? A: Use the Item Name field for current identification and the Notes field for identification uncertainty or alternative possibilities. As you research specimens or get expert opinions, update the identification accordingly. The flexible text fields allow you to document both confident identifications and specimens requiring further study.
​
Q: Can NM Collector manage micromounts and thumbnail specimens? A: Yes. The software handles specimens of any size from micromounts to cabinet specimens to large display pieces. Use the Description fields to note specimen size, mounting type (for micromounts), or display location (for large specimens). Photograph micromounts under magnification and store high-resolution images with each record.
