| I'd go with limonite concretion then. I find stuff like this where I hunt for fossils shark teeth by Holmdel, NJ. They have a wide variety of shapes & slightly varied composition, so they sometime ... | |

| Looks more like a homogenous rock / mineral to me from your pics, and I'm not seeing any mica or garnet either. Although eroded garnets in schist would have a similar surface texture, you would see th ... | |

| Almost certainly NOT platinum - extremely unlikely to just find a nugget of platinum anywhere, and for sure not TX.
It's probably pyrite, aka fool's gold, but it is impossible to tell for sure base ... |

| Yeah, this isn't really the place for your questions.
I will say that you should be more concerned about the hardness & durability of the stone that you use. There are lots of inexpensive stone ... |

Forum: What is it? - Where is it from? Posted: Feb 23, 2021 16:56 Subject: Re: I want to know this stone |
| Looks like carnelian or sard, which are basically just slightly different forms of Quartz. But they wouldn't be an 8.5 hardness and should be closer to 7. An 8.5 hardness is quite high, so I would try ... | |

| Could be from Chester County, Pennsylvania. Most of the PA rutiles have striations like yours, and similar twins occur there as well.
I have a lot of Grave Mountain rutiles & have a focus on th ... |

My word of advice to you would be to stick to sellers loca ... |
