I recently found a nice piece of tumbled cat’s eye at a geo store and I wanted to try and drill a hole through the center of it and make jewelry out of it. Is it possible to drill through this cat’s eye, or would it be too hard? If it is possible, is there any particular technique/drill bit I should be using?
Cat’s eye is a form of gemstone, it’s not literally a cat’s eye.

=O Oh my gosh…that’s so morbid/
Yes. You basically abrade a hole through it. If you don’t use coolant or some method to keep the temperature down, it will break though.
The basic original method was to use an abrasive like a powdered metal oxide, and use a small stick (about like a toothpick) as a drill, twirling it to grind the powder into the stone. Modern methods use the same idea, just with higher tech tools to make it easier and and quicker with a smoother, more refined hole.
LOL. Maybe you should have made it clear to those unfamiliar with gemstones that a cat’s eye is a type of rock. It might have helped to put this in Geology instead of Geography as well.
