Vol. I · The carbon crystal with a paper trail
Jewels Hidden Depths
Secrets beneath the sparkle: eight named ranks from Diamond Beginner to Diamond Master, twelve scroll-to-finish essays, and a five-era timeline that starts in ancient India and ends with traceable supply chains.
Twenty-five dates down one vertical spine
Diamond Timeline keeps the active era at the top. Arrows step from period to period, and a jump lands on the first or the last. Ancient Diamond History through Diamonds in the 21st Century each hold five events, oldest at the top. Every stop is a date, a title, and a short note.
- Ancient India Indian sources open the record, set as the oldest notes in the first era.
- Antwerp The trade city’s role sits on the spine as a dated stop with a short note.
- Kimberley The rush is one event among the five in its era, not a separate gallery.
- Round brilliant The cut appears as a dated milestone beside the stones that made it famous.
- Kimberley Process Traceable supply chains close the run, with diamond materials in technology among the later notes.
A home rank tied to quiz completions
Diamond Journey leads with the level name, a progress bar, the percent through that rank, and the line “X of Y quizzes passed.” Under it, one essay is drawn at random from all twelve, and Quick Diamond Fact rotates lines such as the 4Cs or how natural stones form under mantle pressure. Library, Timeline, and Challenge are the three shortcuts.
Nothing you read moves the rank. Only finishing every quiz in a level — any score — opens the next one, from Crystal Explorer through Cutting Specialist to Diamond Master.
- Eight named ranks, Diamond Beginner through Diamond Master
- Four quizzes in the open rank, then the next lock lifts
- Any completed score counts; essays never do
- Shortcuts: Library, Timeline, Challenge
Twelve essays that earn Read at the last line
Diamond Library searches by title. Each card shows the tag, a one- or two-line brief, and a reading time. Scroll the full piece and it is marked Read. Opening it halfway leaves it unmarked, and reading never changes your rank.
- All ArticlesThe full shelf of twelve, before any subject cut.
- Diamond OriginsFormation, kimberlite, and how natural stones grow under mantle pressure.
- Diamond PropertiesSparkle, color causes, and the crystal itself.
- Cutting & GradingThe 4Cs and the work of the cutting room.
- History & IndustryFamous stones, lab-grown stones, and the modern trade.
Thirty-two quizzes, four locks per rank
Diamond Challenge lists every quiz. Filter Easy, Medium, or Hard, or by Origins, Properties, Grading, History, and Industry. Each question shows right or wrong plus a short explanation. The result screen keeps your best percent.

A crystal with a paper trail
Jewels Hidden Depths treats a diamond as a carbon crystal with a paper trail. The home screen, Diamond Journey, names your current rank, fills a bar, and counts quizzes passed out of the set for that rank. A recommended essay and a refreshable fact sit underneath, with jumps into the library, the timeline, and the challenge. Nothing you read moves the rank. Only finishing every quiz in a level — any score — opens the next one, from Crystal Explorer through Cutting Specialist to Diamond Master.
