Explore. Learn. Price.
The app is organized around two focused modes: Gemology for reference and identification, and Gem Prices for per‑carat pricing rows. Together, they cover the questions you ask most often.
- Minerals list with search, filter chips, and sort tools.
- Quick facts for fast identification: hardness, SG, optic type, and system.
- Expandable sections: crystallography, occurrence, optics (advanced), and chemistry.
- Old names & synonyms help you match historical labels and trade terms.
- Gem pricing with color-based rows, carat-size breakpoints, and occurrence categories.
Gemstone pricing, integrated
Use the pricing database as a fast reference when you’re comparing stones, validating a quote, or learning how price changes with color and size. Prices are shown per‑carat in USD, with multiple rows per gemstone.
Searchable catalog of gemstones
Jump straight to the gem you need (Alexandrite, Ruby, Aquamarine, and more) and see how many pricing rows are available - then drill into detail.
Color-based rows with descriptions
Each row includes a color swatch and a text description, plus context like occurrence category (e.g., rare vs common) to help interpret the range.
Carat breakpoints
Compare common breakpoints like 1ct, 3ct, 5ct, and 10ct side‑by‑side. When data is missing at a size, the app shows it clearly.
Made for quick decisions
The layout is tuned for “glanceable” pricing: a quick scan gives you the spread, the category, and the sizes that matter - without digging through long tables.
