When crafting jewelry - how important is the jewelry mount?

[Conan's Might]

Hi guys,

As the title says, how important is the jewelry mount when crafting jewelry?

Will it utimatley increase the skill bonus if you use a better mount?

Thanks

The mount can make a difference of up to 0.8 (on top of everything else)
