Gems

Gems are the rarest and absolute most valuable currency. Sources include:

* You'll receive 3 of them at the end of the tutorial, when you go up the ladder.
* Cracked Sediments will very rarely give you a gem.
* Chests will very rarely give you a gem.
* Watching Ads can give up to 5 gems a playing session, if you play the game on mobile (every web-based version of Gold Digger FRVR appears to have its ads broken).
* You can also attempt to hack the game

Uses are listed below, with this writer's rating (1 is awful, 5 is awesome):

* (5) Tool Upgrades for 1-4 gems: Each pickaxe/drill you purchase has one upgrade you can buy with gold and a second upgrade you can buy with gems. While the upgrade is small, everything in this game is mining and it will pay for itself.
* (4-5) 3 more rocks for the tent costs 4 gems: If you are lucky it can be VERY worth it as the tent can give objects worth MUCH more than 3 gems. VERY rarely, you can get a gem, 15 gems, and even **50 gems**!!! However, the chances are very low but spending 3 gems for 3 rocks it worth it most of the time!
* (4) Elevator Shaft for 1 gem: Elevator shafts are permanent, which is very handy. They only go 50 spaces so don't use a bunch vertically unless you're getting them for 'free' via ads (besides, you fall much faster than they can go down). Instead, place them horizontally since there's no other way to rapidly go left or right except by elevators.
* (2-4) Bundles for 1 gem: These refresh every few hours but can offer several items each normally costing a gem so this can be a good deal.
* (3) 3X Level-up Stars for 1 gem (only lasts a period of time but if your goal is to get all the skills in the game, achievements from explosions and mining deep won't get you there so this could be useful).
* (2) 10X Level-up Stars for 3 gems: Same issues as the 3X version, only more expensive.
* (2) You can buy a Power Hat for 1 gem (only blocks a single hit but gives you gold when it breaks).
* (2) Sonar (5 uses) for 1 gem: This works similar to the marker you automatically get after dying, leading you to your tombstone. It will pick up super ore extractors and other things, though. It also lasts for a minute at most.
* (2) Repair Kit for 1 gem: If you absolutely need it, you can buy it but it's probably worth watching an ad for instead. If you can't watch ads, just mine within the 100 foot depth layer for cracked sediments, you should pick up more Repair Kits than you spend.
* (2) Rock Transformer for 1 gem: First rock that goes in 'sets' the transformer and the next 100 rocks that go in will change into the type of the first. In practice, this is hard to use and consumable so not worth spending a gem on.
* (1) Chests for 1-3 gems: Given that gems are a *rare* drop from chests, this is pointless. Mine for cracked sediment and you'll find more chests than you can carry.
* (1) Gold Magnet for 1 gem: This only lasts 30 minutes. This is worth a 30 second ad but never worth spending a gem on.
* (1) 50 coins for 1 gem or 500 coins for 3 gems: Possibly the worst deal in the entire game. 2 minutes of mining cracked sediment will give you far more gold in the form of items to sell. Never buy this. In fact, it is a better idea to spend 1 gem to buy a repair kit and sell it for 200 coins.

## Trivia

• There is a glitch where when the get gems from a box or Chest, it disappears after logging off. It is unknown if it happens to everybody or in a type of platform. (This probably means spend it before you leave)
