This is an unpolished slab of Stone Canyon Jasper/Agate. It is roughly 3 1/2" x 3 1/4" 6 mm thick. It weighs 3.1 ounces, or 88 grams. This was from an old-stock collection and a prior owner put templates on one side (last photo). They will come off but might take a little effort or grinding off. Photos include wet (to get an idea of what they will look like when polished) and dry.

This is another slice of Stone Canyon Jasper/Agate. It measures about 3 3/4" x 3" at its widest points, and about 5.8 mm thick. It weighs 2.8 ounces, or 80 grams. There are stuck-on templates on the back from a prior owner - they should be able to be removed with a little work, or just some grinding. You can also see on the front, in the 2nd photo close-up, what looks like '75' with an aluminum pencil. That should polish out.
