Pretty cool, unfortunately fractures can be a problem in Montana Agates.

Last picture has at least one safe zone for a cab. As slabs they are all nice.

Any line or color band is a possible fracture. Montana is challenging. First, a person needs to be good at reading the rock. A high percentage of Montana is duds. Next designing around the areas like to fracture and last, the grinding and sanding needs to be thorough because a person will end up with polished scratches. It is still one of my favorites.

Kept in the bathroom you say?! Well, then it's a good thing all those were cut "flush"! Couldn't resist! Sorry for the cracks...a bit disappointing, but I'm sure you'll be "showered" with praise for the effort!

Agatewhisper, you could quartz cap the back and then shape as desired. This would make a really nice display piece.

It has some beautiful "Turtlebacks" in the stone also.... As said fractures live in Montana moss agate... I will be cutting 16 of them today, so will be seeing a few also....Hahahaha.. Mostly that is why Montana moss agate are cabbed small....

Agatewhisper, RTH has a demo for you that shows what to do and the material needed. Type in "How to use and make a quartz cab" in the google search box. Sometimes you can find several slabs of optical quartz on RTH or locate a quartz blank used in the computer industry to make wafers. If you can't locate quartz use optically clear glass instead.

Thanks for the tip! Have never tried anything like that before.
