Can the route be completed?
A crystal above the safe cold limit has no completed-run value if you cannot return to sell it.
Mine a Mountain Crystals Guide
A checked guide to the confirmed role of crystals in Mine a Mountain, the information shown by official game media, and the values that still require in-game verification.
What official sources show
Crystals are the resource behind the sell loop
The official listing tells players to mine rare crystals and sell them for cash. Official promotional media also shows crystals at different heights and displays crystal weight in kilograms.
ConfirmedMechanic and visual presentation only; the media does not establish a complete rarity or price table.
Route decisions
How to reason about a crystal without a fake price table
A useful crystal decision includes whether you can reach it, mine it, carry it, return, and sell it. Visual rarity alone does not prove the best cash route.
Does it fit the current Backpack?
Official media shows crystal weight, so capacity can affect whether a find completes the sell loop.
Compare completed cash returns
Record cash only after selling, then compare full route time instead of judging by color or height.

Visible details separated from unsupported conclusions
These observations come from Roblox-hosted promotional frames. The right column records where the evidence stops.
| Visible observation | Limited conclusion supported | Not established by the image |
|---|---|---|
| Crystal-like objects appear at several mountain heights. | Height and route access can be part of a crystal decision. | No spawn table, zone boundary, or height-based value formula. |
| The media uses multiple colors and shapes. | The game presents visually distinct crystal finds. | No official rarity names, order, odds, or sell-price ranking. |
| One frame labels a crystal as 90.3 KG. | Weight is a visible property in official marketing. | No price-per-kilogram rule or proof that heavier always means more profitable. |
| A character is shown with a backpack and pickaxe. | Mining and carrying belong to the advertised crystal loop. | No exact tool power, backpack capacity, or optimal loadout. |
