Nope.
As you level up, you will be able to level up your dragons more. You simply need to grow treats and feed them.
You either need to breed new eggs in the breeding cave, or buy them in the market.
You will need to just work on leveling up. It shouldn't take long. The first gemstone dragons come available at level 12.
There are actually a couple of dozen gemstone dragons in DragonVale. They are a type, like the fire dragons or earth dragons. You would need to know which gemstone dragon you were trying to breed to find out who the parents should be.
You have to be at level 15.

Well to make a swamp dragon you need water and earth. You get water at level 14 and you also can buy it at level 14. So it's level 14.
You need to have the breeding cave and at least two compatible dragons. After you build the cave, tap on it, and two lists of dragons will come up. Pick one dragon from each side, and tap on breed.
The level of your dragons is not dependent on your user level. You need to buy shrines for each element, and then meet the requirements for that element.
You simply buy the breeding cave and select the two dragons you want to breed to try for a gemstone dragon. The only one out right now is the pearl dragonbirthstone, pearl), but to breed it you need the snow and seaweed dragons to put in the breeding cave. Also, you can buy gemstone dragons on the store for different gem amounts. The Pearl dragon can be bought for 1,475 gems. You have to get to a certain level to be able to get it though, although I don't know what that level is. I read that you have to be level 17 but I am currently a level 15 DragonVale player and the Pearl dragon is in the store available for me to buy. I owe all of my information credit to an app I have called "DragonVale Guide". I advise you to get it for future questions. You can also use it to find people who are willing to become gamecenter friends with you! And it gives you information about not just dragons, it also tells you about objects and gives you strategies on how to earn gems, coins, and experience! Just search "DragonVale" in the app store and you will see an app that has a rainbow egg with a background as the sky for its app picture. That is the all-wonderful app! Enjoy! :)
For a quake dragon you need to breed earth with a regular lightning dragon, and moss I'm not sure.
Lvl 10 fog left and Lvl 10 lava on the right. This has a 17% chance of working. It is the most effective method
