Out of all the leather types in the world, crocodile only makes up around 1% of the total amount of the leather trade worldwide. With the supply low, this makes the skin of a crocodile a luxury and delicacy.

Have you ever had a tattoo?  That bumpy raised skin feeling is like the way embossed materials would feel.  The raised skin is a convex effect.  It is creating a 3-dimensional effect with the material that it is pressed upon.  The process of embossing and debossing is similar.  The main difference is that embossing has the leather with the design on the bottom of the leather, pushing the leather up as it goes through a roller.
