Hi everyone, hoping for some help (or confirmation) on this stone.

While I believe it’s a Garnet, I’m no expert. I’m considering sending it to a lapidary or an expert for evaluation.

Any help is much appreciated!

Since you have a scale can you rig up a Specific Gravity unit?
https://www.mindat.org/mesg-338875.html

A rare earth magnet to test for magnetism?

Why do you believe it's a garnet?

More information would be useful.

I'm a lapidary and in no means an expert in all things rocks and minerals. Yes why do you believe it to be garnet? The first pic looks like it has been oiled, was it? If you know for sure the area it was found a local lapidary may have worked with the material and has already identified or knows. But if you do not know for sure where it is from, find an appropriate lab or gemologist. Building a inexpensive specific gravity instrument can always come in handy like suggested.

Visually it does look like a classic piece of garnet rough. But, as we know that is not really a very concrete statement. It also looks to be of very low quality, so not much likelihood of a good lapidary result.

Hi everyone! Thank you for the great ideas.

I believe it to be a garnet due to location. It’s from the Missouri River in Montana. It’s not been oiled, but I had soaked in in vinegar to get some of the dirt out of the cracks and took the picture after washing it with water, still wet.

I’ll put together (as recommended) a specific gravity system and post my results.

I’ve been digging for sapphire for 5 years in the same region, but haven’t had anything this exciting, ever!

Thank you all!

At first I was going to say it looked like a well aged rib-eye steak. But here lately every one is so touchy. Clearly it is not looking at the scale image. I was looking at images last night on mindat and I have to agree with you and @1bwana1 that most likely a river worn garnet and your find locale info. So no exciting sapphire finds? Or not found in the area you mentioned finding this.

Steve and Greg are the experts here. They deal in rough stones.

Ha! Honestly, the rib eye comment would have made me laugh. I agree though, folks are a bit cooped up and edgy and easily offended -not this guy though, and I appreciate the humor!

I’ve found a few sapphire, nothing amazing, but I’m having fun with the hobby. I’m loving the blue skies, outside time and never knowing what little treasure might present itself!

How are you testing it, III?

It looks a lot like some rough we have that is Brazilian green dendritic moss opal. The photos look like they are back lit, very florescent vibrant green. Found where? Yes how have you tested it to conclude its not Chrysophase.

How do you know it is not gen chalcedony? It sure looks like it may be. If it is you have to know what the coloring agent is. If it is Nickle then it is Chrysoprase. How have you tested for that to make such a strong statement that it is not?
