## What is Stone Cabinet?

Brush away the soil with your finger and dig up minerals. Display what you find in a cabinet that's all your own, polish specimens to a finer grade, and cut spare stones into gems.

DIG IN TWELVE COUNTRIES
Japan, the USA, Mexico, Brazil, Morocco, China, India, Madagascar, Australia, South Africa, Tanzania and Myanmar. Pick any of them on the world map; every country is open from the start.
Only stones really found in that country come out, checked against museum and geological-survey sources. Each country's specialities turn up a little more often, and finding every stone from a country earns its stamp.
Trace the little mound, feel the brush catch on stone, and watch rare finds glint through the dirt.
Geodes come out closed. You won't know what's inside until you crack them with a hammer.

COLLECT
106 minerals and gems: quartz, amethyst, jade, pyrite, fluorite, ruby, sapphire, rough diamond, Paraíba tourmaline, kunzite, iolite, moss agate, meteorites and more.
Every specimen is one of a kind, with its own size, grade (Fair to Museum) and features like double terminations, phantoms and rainbows, and you can see it in the stone. A single point, a group on rock or a cluster: how it was found changes its look too. Each find is compared with the ones you already have.
The guide tells the story behind each stone's name and color, and keeps track of the localities you've dug it at. Home shows a stone of the day.
Complete sets such as the twelve birthstones, rainbow gems, the quartz family and stones fallen from the sky to earn titles, and show any set off in a theme case with a named spot for each stone. "Your goals" on the home screen shows what to aim for next.

POLISH AND CUT
Release spare specimens for shards, then spend shards to polish a specimen by rubbing it with your finger and raise its grade (up to Fine; Superb and Museum grade only come from digging).
When a stone turns up again, cut the spare rough into a gem with one tap. Rubies become ovals, emeralds get an emerald cut, opals a smooth cabochon.
Each cut is graded Fair, Good, Very Good or Excellent. Your gems go in the jewel box: 54 to collect.
Cut gems can be polished with shards too, one step at a time up to Very Good (no draw).
Your best specimen of each kind, favorites and displayed pieces are never used.

DISPLAY
Tilt any specimen with your finger to take a closer look. Shine UV light on fluorite, calcite, ruby or Yooperlite and watch it glow.
Your cases are glass-topped walnut cabinets with twelve compartments. Name each one, arrange your favorites, and share a picture sized for posts or stories.
Every label has the locality, hardness, formula and a short fact, and the rarer stones have two.

DIGS AND PURCHASES
A free dig comes back every hour, up to five. Your first 15 digs are free.
The only purchases are packs of 10 or 100 digs.
The finds and odds for every country are shown in the app. If 19 digs in a row in the same country bring nothing rated 3 stars or better, the 20th is guaranteed to be. Digging ten bought digs at once always includes one 3-star or better.

No ads. Your finds are stored on your device, and no account is needed.
Specimen images are artwork made for this app; they are not photographs of real specimens. The map is based on Natural Earth (public domain).

## Version history (last 5 releases)

### 3.6 — 2026-10-30

Every stone you dig now reads like a museum specimen.
- Each specimen page has an "About this stone" card: where its name comes from, why it has its colour, how to tell it from look-alikes and more, open and ready to read.
- Labels show the crystal system and a hardness you can picture (fingernail, coin, knife, glass).
- New finds show their formula and a short fact as you dig them up.
- We checked every stone's notes and fixed mistakes, and re-shot or added 36 photos, so the stones you find most often come in more looks.
- When cutting gems, you can see how many more cuts your rough allows.
- Your rank on Home is shown in words and a bar instead of a number.

### 3.5 — 2026-10-29

You can now pick one stone to look for.
- Open a stone you haven't found yet in the guide and tap "Look for this stone". It goes to the top of your goals on Home.
- Your goals also show the countries where it is found, so you know where to dig.
- When it turns up, you'll see "Found the stone you were looking for!", even when you dig 10 at once.
- The tip under the dig site now shows on your first 3 digs only.

### 3.4 — 2026-10-28

The dig site is now real ground from each of the 12 countries.
- Brush away riverbed gravel in Japan, desert soil in the USA and more, each true to where the stones are found.
- Soil you haven't brushed stays put, so each stone comes up just the way you dug it.
- Six new sets: Stones That Play with Light, Mohs Scale, Copper Minerals, Colors of the Mine, The Beryl Family and The Garnet Family.
- A cleaner Home screen puts the country and the dig button front and center.
- Show only the stones you haven't found yet in the guide.
- Specimen pages now have a "More about this stone" section.
- While you wait for digs, cut gems in the Jewel Box.
- Countries where you have found every stone are now marked Complete on the map.

### 3.3 — 2026-10-26

Five new stones loved around the world.
- Moss agate, Yooperlite, dioptase, adamite and demantoid, each from places where it is really found.
- Yooperlite and adamite glow under UV light.
- Demantoid can be cut into a gem, and fills the green spot in Rainbow Gems.
- The big button on Home always digs one; Dig 10 at once sits just below.
- Switching tabs takes you back to where you were.
- Filter your cabinet list to favorites or to stones not on display.
- With Reduce Motion on, stones no longer sway and screens no longer shake.

### 3.2 — 2026-10-25

More than one look for each stone.
- A quartz can now be a single point, a group on rock or a cluster, depending on how it was found, and double terminations and phantoms show in the picture. 138 new photos for the stones and colors you find most often, and your own stones get their new looks too.
- A new 5-star stone: kosmochlor, found in Itoigawa, Japan, and in Myanmar.
- A tidier result screen: the stone's name and grade are never hidden behind the buttons.
- Up to 250 display cases, and you can put all your stored stones on display at once.
- Sparkles and light rays now settle after a few seconds.
- Small fixes.
