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 4 minutes until 01:59:00 it will only cost 2 Gems. There is a glitch that allows players to spend 1 gem when the timer shows 00:00:00.
Free Gems can be received via friends who gift 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 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 awards 2 and a gold trophy awards 5 . A bronze trophy does not award you any .
Gems can be obtained by using the Gold Spin wheel (which is done by coming in first place in a race), or on the Bonus Spin wheel (which you only get if you win a Kairos fragment you already have on your first spin) at the Dragon Track. You can be awarded one to two gems, depending on which one the spinner lands on.
Gems can be earned as currency instead of by Gemstone Dragons in the Gemstone Island. These dragons may earn a maximum of 1 per week when fully levelled (level 10).
Gems can be obtained if a goal that requires the user to breed an epic, opposite, or gemstone dragon is completed. The gems awarded range from 1 to 5, depending on the difficulty of the particular dragon in question to breed.
Gems can also be obtained by sharing the completion of goals to Facebook or Twitter as of March 26, 2013.
