Need help in cutting rose quartz raw chunk stones

[annemarielei]

Hello,

Do you have any suggestions how to professionally cut rose quartz raw chunks. The purpose is to make a horizontal line cut and transform it to a card holder / stand. The cut would be more like removing a thin slice out of the stone.
I understand this is made with a blade, but do you have any suggestions for specific tools or machines for a beginner.
I have never cut gems or minerals, but I am eager to learn a new skill.

Thank you in advance.
