DragonVale Currency

DRAGONCASH
DragonCash is the currency of DragonVale. It is used to purchase nearly everything in game such as Treats, Habitats,Decorations, Islands, basic Dragons and Buildings. Paid DragonCash DragonCash can be purchased from the Market for real currency. Like Treats and Gems, you are offered more "incentive" DragonCash when you spend a larger sum of money at one time. The currency and rate changes by level and country.

Making DragonCash
The most common way to earn DragonCash is to put dragons in Habitats and collect the money when it fills up. An icon of an empty treasure box will appear when a habitat is around one-third full, and will switch to an icon of a treasure box over flowing when the limit is almost reached.

DragonCash can be collected by tapping on the icon or by tapping on the habitat before enough DragonCash accumulates and tapping the "Collect" button.

DragonCash can also be earned from selling unwanted dragons, racing in Dragon Track, and by finishing events in the Colosseum.

Gem Prices
The purchase price for Gems are constant throughout game progression. Gems can be purchased for:

Gem Value
One Gem is equal to whatever time is left  up to  an hour. This means if there is 02:03:00 (hh:mm:ss) left for the egg to hatch or breed, it will cost 3 Gems to finish it (2 for the hours + 1 for the 3 minutes). However, if you wait 5 minutes until 01:58:00 it will only cost 2 Gems.



Obtaining Gems
Free Gems can be obtained by friends gifting them to you. An infinite amount of Gems can be received daily (assuming you have an infinite amount of friends willing to gift) but only 3 Gems a day can be sent to people on a player's friends list. See the Strategies page for additional information on gifting Gems.

The Dragonsai Gifting Tree can be purchased for 100 gems and will allow the player to give away 3 additional Gems per day.

Free Gems can also be obtained by winning in the Colosseum. A silver trophy is worth 2 gems and a gold trophy is worth 5 gems. A bronze trophy does not reward you any gems.

Gems can also be obtained by winning races at the Dragon Track, though it is very rare.

Gems can also be gained by Gemstone Dragons in the Gemstone Island.

Please be reminded that the Friends page is the ONLY acceptable place outside of a user's profile and personal pages for friend and gem requests to be posted.
