Sugg on diamond saw blades

Hello everyone,
I just purchased a 6 inch HiTech trim saw. I am planning on cutting Lake Superior agates and also Larimar. I know these 2 stones are totally at end of the spectrum in hardness. So my question is what types of 6 inch blades would you suggest. I understand that I probably will have to purchase 2 different types of blades.

Thanks
