Loupewise (formerly GemID) is a complete toolkit for gemstone identification and gemology study. Enter your instrument readings and it narrows the candidates; catalog your stones; generate examination reports; and prepare for your diploma exams — one app across your whole path, from first flashcard to first client report. Loupewise is an educational reference tool for gemological observation. It is not a substitute for professional laboratory testing or a certified gemologist's opinion. IDENTIFY STONES FROM YOUR OBSERVATIONS Loupewise comes to the workbench with you. Enter your refractometer, hydrostatic scale, UV lamp, polariscope, and loupe readings, and the app cross-references them against 130 gem species and varieties — returning only the candidates genuinely consistent with your data, with the full elimination path shown. Read RI 1.544 and SG 2.65? Loupewise shows that's consistent with quartz, and the one test that narrows it further. The logic is transparent; the reasoning stays yours. NATURAL VS SYNTHETIC & TREATMENT TESTING A two-phase origin workflow: enter inclusions, growth structures, fluorescence, and spectroscopy observations, and Loupewise walks the differential for natural vs. synthetic and heated vs. unheated. Treatment coverage includes heat, diffusion, glass-filling, fracture-filling, and coating. TRACK YOUR COLLECTION Save each identification with its readings and elimination trail. Build a catalog of your stones you can search and revisit. EXAMINATION REPORTS Turn a saved identification into a clean, shareable examination report with your observations, the candidate reasoning, and your notes — for your records or your clients. A MAINTAINED REFERENCE DATABASE 130 gem species and varieties across every major family — corundum, beryl, chrysoberyl, garnet species, tourmaline, quartz, feldspar, opal, jadeite, nephrite, spinel, topaz, peridot, zircon, tanzanite, and more — with refractive index, specific gravity, optic character, pleochroism, fluorescence, and the diagnostics that separate look-alikes. Where the exam bodies publish different reference values, Loupewise shows both, tagged to the exam that grades you. PRACTICE EXAMS FOR GEMOLOGY STUDENTS Preparing for a diploma? Loupewise includes practice exams built for the GIA 20-stone, Gem-A FGA, and FEEG European Gemmologist exams. Identify unknown stones under exam conditions, and a readiness score tracks how prepared you are across the property categories examiners test. DRILL WITH SPACED REPETITION Build property recall between sessions. 21 question types across refractive index, specific gravity, optic character, pleochroism, fluorescence, natural vs. synthetic indicators, treatment detection, and key differentiators. Filter by family, color, instrument, or confusion pairs. Spaced-repetition scheduling surfaces the cards you're weakest on. 15 LANGUAGES Available in 15 languages. 7-DAY PRO TRIAL — NO CARD REQUIRED Every account starts with a full 7-day Pro trial. After it, continue free with daily drills, full instrument input, and candidate results. Hobbyist adds unlimited drills, named candidates, and your collection; Pro adds examination reports and the full exam simulators.
