Countertop Pen Materials

Hello,
I love to make pens out of various materials and the tru-stone marble looking blanks are expensive. I don’t have a carbide blade, but can get one for my mitre saw which I use to cut blades with a jig. You don’t have to go to a quarry. If you want free samples you can find them at Home Depot as they get them for customers to take home, but you have to look in the drawers in the back (just ask for counter samples). There is all colors and some have shiny pieces. Some are thicker than others. Give LOWES a try also.

I NEVER SEE GRANITE BLANKS BEING SOLD, CAN THESE BE TURNED? HOW ABOUT SILESTONE? QUARTZ? ALSO CAN THESE BE TURNED? I HAVE CARBIDE TURNING TOOLS. I would use Acrylic sandpaper and finish.
