Daily jade lessons & field ID
JadeScope is a pocket classroom for jade. Three minutes a day, from zero to a trained eye. Fully offline — no account, no network requests. A lesson a day Eleven lessons along a guided path, from "what is jade" to certificates and common fakes. Finish one, stamp it, and keep your streak visible. The jade atlas Thirteen entries — jadeite, nephrite, serpentine, quartzite and more: physical properties, spot-it-in-a-second cues, traps to avoid, and look-alike comparisons. Hand-drawn line diagrams make tough concepts visual: jadeite granules, color roots, acid-etched networks. The 5-step field check Standing at the counter, unsure? Five checkboxes (weight → ID cues → certificate) lead to a three-level tendency and an NGTC lab-submission card. When in doubt, always have a stone tested by a professional lab. Quiz drills 33 questions with picture rounds, ordered from easy to hard. Wrong answers come with instant explanations and a link to the atlas entry; mistakes enter a wrong-answer book and leave after two consecutive correct rounds. Learn to decide Every buying-decision topic lands on a verification action: read the certificate, run the check, submit to a lab. Entries follow GB/T 16552-2017 and the Systematic Gemmology reference. Fully offline by design: your learning history never leaves your device. JadeScope teaches identification — it does not replace professional testing. Before you spend big, send it to a lab.
