About Gemmology Rocks Gemstone Advent Calendar 2026
Gemmology Rocks teaches gemmology from the UK, and its fifth annual calendar is a night-blue box of 24 doors with a cut gemstone behind each, every one sealed in its own clear collector pot. The stones are reclaimed or pre-owned rather than freshly mined, and each comes with a lesson: an online interactive calendar opens a short course on the day's gem, 24 lessons in all.
Display boxes to house the collection are in the set. 249 GBP from the Gemmology Rocks shop, on sale when checked on 20 October 2026; ships from the UK, with US prices including tariffs.

Gemmology Rocks Gemstone Advent Calendar 2026 by the numbers
How each one is countedEvery figure is computed from the record at build time and set against the median of the same season and the same kind of contents. Door price is the price on the box over its doors; the value multiple is what the contents come to at retail over that price; full size is the retailer’s own marking. Where the record cannot support a figure, the page leaves it out rather than guessing.The definitions, one by one →Each figure against the median of this season's art shelf — 40 calendars. Green is the better side of the median, red the worse; the median is printed so you can disagree.

Our Gemmology Rocks Gemstone Advent Calendar 2026 review
Our verdict
Twenty-four cut gemstones, reclaimed rather than newly mined, each in its own pot, with a lesson a day on the stone you have just opened. It is a short gemmology course in calendar form and priced like one; the catch is that nobody knows which 24 stones until the doors open.
Reviewed by Max Zeshut · 2026 season · How we review
What works
- Real cut gemstones, not tumbled pebbles
- A lesson for every stone turns it into a short gemmology course
- Reclaimed stones, each in a pot you keep
What does not
- The 24 stones are not named in advance
- Reclaimed stones can carry small marks
- A specialist price for a specialist box
