According to wikipedia geode are geological secondary structures which occur in certain sedimentary and volcanic rocks. They are themselves of sedimentary origin and are formed by chemical precipitation. Geodes are hollow, vaguely spheroid to oblate masses of mineral matter (which may include crystals). 
Geode banding and coloration is the result of variable impurities. Iron oxides will impart rust hues to siliceous solutions, such as the commonly observed iron-stained quartz. Most geodes contain clear quartz crystals, while others have purple amethyst crystals. Still others can have agate, chalcedony, or jasper banding or crystals such as calcite, dolomite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or broken apart. However, geodes from a particular area are usually similar in appearance.

The geode trend started with geode cake then geode lips and now geode nails!
It is not an easy look to achieve, the design is all free handpainted. I followed the "So nailiscious" tutorial but I decided to give my peronal touch using a different shade and adding clear flakes and gold flakes for a more crystal like effect.
First I applied a white polish to serve as the base. They I outlined the portion of the nail I wanted to paint with a darker shade or (even better) a metallic one that resembles the gold exterior found on certain rocks. I used many shades of blue. To mimic a geode's jagged texture I used clear flakes in different shade applying a thick gloss over it to lock it down.

In particular I used a gold flakes powder for Beauty Big Bang. These gold flakes (product IDJ2430-GD) currently retail for 1.61 euros and come in gold and silver.
