Marvel's Infinity Stones

For my first personal project I decided to make something about the Marvel Universe which is ony of my favourites works of fiction.
It was a good practice at shading thanks to the complexity of the object and the impact that it has on the lighting and material.
The six stones are made after one mesh being deformed with different parameters for each stone, the shader is common to all of them except for the color.
I improved the final render on Photoshop and made some background to make them nicer to see.
