A workshop for stone and glass
The world begins on Aonagi Island.
Find stones. Wash them. Break them. Observe them. Bring stone and glass together and make something of your own.
Coast, forest, river, cave and abandoned mine. Walk a quiet island and discover the time hidden beneath your feet.

THE WORLD IS BIGGER THAN ONE ISLAND
There are6,239recognized mineral species worldwide.
IMA-VALID MINERAL SPECIES
And there are minerals still waiting to be discovered.
Go in search of stones you have yet to meet.
The First 72 was not the finish line. It was the first set of discoveries placed into this world.
Source: valid mineral species in the official IMA-CNMNC list. A global count, not the number of minerals in the game.
The surrounding stones are decorative mineral imagery.
Beyond the sea are islands shaped by entirely different geology.
Because of the extraordinary geological diversity across the region, researchers have come to call it The Deep Time Archipelago — 深時諸島（みときしょとう） in Japanese. It is a nickname, not the formal geographic name.
ENTER THE DEEP TIME ARCHIPELAGO
AONAGI ISLAND / SEASON 1
The first island.
Beneath Aonagi’s calm blue sea lies a geological history hundreds of millions of years deep.
- Ancient metamorphic basement
- Volcanism
- Granite intrusion
- Pegmatites
- Hydrothermal activity
- Uplift and erosion
That is why the coast, river, mountain, cave and abandoned mine can each reveal different stones.
Season 1 begins here.
DISCOVERY
A stone does not always tell you its name when you pick it up.
- FIND
- WASH
- BREAK
- OBSERVE
- IDENTIFY
A gray rock may reveal a vein after washing. A fracture may expose a crystal. Observation brings you closer to its identity.
Not every stone contains something rare. Ordinary rocks matter too.
That is what makes a true discovery feel special.
STONE & SCIENCE
An imagined island. Real stones to discover.
Check names and origins against scientific sources. Keep the provenance of photographs clear, and distinguish them from generated images. Meet a child’s curiosity with care.
KEEP / DISPLAY / SELL / MAKE
What happens next is your choice.
A stone you find can be kept, displayed, offered for sale, or brought together with glass to make a work of your own.
Enjoy a stone’s natural beauty. Bring your own vision to the materials and make something new. An ordinary stone may become part of a work someone never forgets.
Making creates new value.
Name your work. Display it in your gallery. Encounter what others have made at the museum by the sea. Exploration, making and exchange become part of the same life.
WHERE IT ALL BEGAN
The First 72
The first 72 collection entries: encounters with minerals, rocks, fossils and varieties.
A record of where the world began, not a count of 72 formally recognized mineral species.
The First 72 — where it all began.EXPLORE THE WORLD
A QUIETER KIND OF GAME
You do not have to fight.You do not have to take from others.You do not have to hurry.
Watch the sea. Look for stones until sunset. Walk through the forest. See what others have made. Grow your own gallery, slowly.
Rarity and price are not the only measures of value. This is a world where you can cherish what matters to you.
You decide what to treasure.
