I have all of this stuff that I can't find the hardness for. I can fake it as it's mostly jasper but if anyone has a good source for data I would sure appreciate it.
Cave Creek Jasper
Cherry Creek Jasper Picasso
Munjina Stone
Outback Jasper
Porcelain Jasper
Rooster Tail Jasper
Viper Jasper
Yellow Jacket Jasper
Succor Creek Jasper
Imperial Jasper
Rocky Butte Jasper
Indian Blanket
Navajo Blanket
Indio Agate

Well the thing is it can vary so much within the material. Especially on the jaspers.

81 views and not one answer Maybe because there really isn't 'one' answer. Not everyone is going to be familiar with all of those trade names. Generally speaking, jaspers and agates tend to be in the 6.5 - 7.5 Mohs hardness range. However, some rocks labeled as 'jasper' are not actually jasper and can be much softer.

Jokes aside,it's fairly easy to determine mineral hardness. Use this Mindat discussion as a guide: www.mindat.org/mesg-178691.htmlRemember that many stones called "jasper" aren't really jasper and many others called "agate" aren't really agate. It's best to test each type yourself. Examples from your list that are soft and not jasper would include Cherry Creek and Picasso. I'm not familiar with all they stones you list so there may be others.

It was a good response, for some reason you choose to ignore it.

I have no expectation that anyone let alone everyone would be familiar with all of that. I figured someone may be familiar with any one of them. I do know what hardness range that they tend to be that's why I said I could "fake it", I also know that there are some misnomers thus the main reason for the question. I thought it would be helpful for myself as well as others to know their hardness with some certainty. Here's another, only because typing is cheap: Black Forest

Ok Let’s all be civil For what useful purpose is this information being gathered? Do you have pictures to go with the material names? For instance crysocolla can vary wildly in hardness. Metal is a great go-no go tester to me for polish. If you can scratch the surface and remove powder with a small screwdriver or pocket knife, it’s not gonna polish easily in a tumbler.

The purpose is to compile a database for reference. I will either tumble or slab/cab this stuff eventually (no particular hurry, I have so much in process and on deck so it will probably be a while until I get to them). When I don't know the properties of what I am dealing with I do a steel nail test to determine if I am going to just dissolve stuff. It's certainly not the end all be all test though. I would get a set of those fancy picks, but I am not allowed to have sharp objects lol. Truth is I would rather spend money on rocks.

Black Forest cake is soft and yummy That looks delicious, except for the cherries. Fruit with chocolate makes me boot. Even Tootsie Pops make me sick.
