This is a model of Clash of Clans Premium Gem in 3D. It's a simple and beautiful model.
Gems are a resource primarily gained through in app purchase (IAP). There are other ways to obtain gems, although these methods are rather slow in comparison to purchasing them in the Shop. Small numbers of gems can be obtained by clearing rocks and trees from your village, but this is random and rate of respawn of trees and bushes is quite low. Completing achievements also awards gems. In addition, the top players in the top three clans receive gems from the weekly tournament. Lastly, Supercell occasionally holds competitions on their Facebook page for which they award gems to the winners.
Gems can be used to purchase gold, elixir, dark elixir and builder's huts. They can also be used to speed up upgrades, gold/elixir collection and to finish troop training.
Generally it's a good idea to save your gems for builders huts, as having more builders drastically increases the speed at which you can upgrade your village.
Gems are the premium in-game currency used to advance players' villages. When players first download the game they begin with 500 Gems (250 of which you are forced to use during the tutorial, and another 8 if you rush the buildings and troops when prompted). Additional Gems can be earned in-game by completing Achievements or clearing Obstacles, or purchased with real money. Gems can be used in several ways:
There are several items, such as the Pirate Flag, the Mighty Statue and Builder's Huts, that can only be purchased with a substantial amount of Gems.
Gems also can be used to buy other Resources such as Gold, Elixir or Dark Elixir in varying amounts.
They can be used to instantly finish the Troop training queues in Barracks and/or Dark Barracks.
Gems can also be used to instantly complete the construction or upgrade of Buildings, or Troop upgrades in the Laboratory.
Players can also speed up the production of Barracks or resource collectors such as Gold Mines, Elixir Collectors and Dark Elixir Drills for a period of time using Gems.
Heroes can be recovered or their healing rate can be increased by gems.
