Just finished this calcite thin section, it's a fairly soft mineral so it was easy to make at home with sandpaper, I will probably make a new one soon and switch from coarse grit to a finer grit to prevent having the scratches visible in the final product.
I am not sure what this pattern is called in the thin section but it's quite nice to look at, figured you guys might enjoy it!

That's a cool pattern and nice coloring. Thanks for sharing.
Re: Calcite thin section
Nice! Its crystal twinning. Crystal twinning occurs when two separate crystals share some of the same crystal lattice points in a symmetrical manner. The result is an intergrowth of two separate crystals in a variety of specific configurations (wikipedia).

geo_man,
I you're absolutely right!
I am aware of twinning but haven't learned much about it in thin section, guess I gotta keep hitting the books!
