Store description excerpt
Cooply is your pocket encyclopedia for gemstones and minerals — an authoritative reference covering over 30 stones with gemologist-grade detail. Every entry documents crystal system, Mohs hardness, refractive index, dispersion, specific gravity, rarity tier, and natural color range. A built-in Light Play visualizer shows how each gem interacts with light, while color range cards, optical properties panels, and cut anatomy diagrams turn raw data into something you can see. Build and manage your personal collection with the Register. Log owned stones and wishlist pieces, record carat weight and estimated value, attach your own photos, and add private notes. An interactive world map plots every gem's known origins — from the ruby fields of Mogok to the opal mines of Coober Pedy — so you can trace the geology behind every stone in your collection. The Learn section pairs curated articles with timed quizzes to sharpen your gemology knowledge at any level. An achievement system rewards exploration: earn badges as you progress from First Stone collector to Curator, Sharp Eye, and Gemologist. A daily featured stone and monthly birthstone spotlight keep the catalog fresh every time you open the app. All data lives entirely on-device, so your reference library and collection register are available offline, always. Whether you are a first-time buyer curious about your birthstone, a seasoned collector tracking a rare alexandrite, or a student preparing for a gemology exam, Cooply gives you the depth and tools you need in one elegant app.
