Before anyone asks, she won't be touching the rock again but she touched it last night and is still experiencing tingling in her fingers.
This is a friend's stone and I was given permission to post the pictures to help her to hopefully properly identify it.
- It makes fingers tingle when touching it.
- Origin unknown, it was gifted to her by an old time collector who didn't remember and has since passed, he was in the service and it could be from anywhere.
- It is very dense and heavy 137.8 grams.
- It streaks yellow.
- It is not magnetic.
- It does not cut glass, but scratches it.
- It is very fluorescent.
Any help identifying would be appreciated!
...I'm new here, trying to figure out how to upload images. lol

Here's the link to the Cloudinary Tutorial to set up an account to upload pictures. Follow the directions exactly and you should be able to post your pictures. |

I can't help identify the rock, but it could possibly be just a matter of an allergic reaction. I'm not a doctor!!!
I know of a person who would handle a specific dart and fingers would tingle for days. He finally figured out is was an allergic reaction to the titanium-nitride coating on the set of darts...
Edit - tingling fingers is also a sign of arsenic poisoning...

Good call, jasoninsd. Arsenic is yellow/orange and it can also be in other minerals. |

It is highly unlikely that any poisoning took place from touching it. Orpiment has low bioavailability, even when ingested (3-4%). Acute transdermal poisoning is exceedingly unlikely, as it is even more inefficient. Chronic exposure would be more of a concern. It is far less toxic than other forms of arsenic (such as arsenic oxides). The average person would have to ingest several grams of orpiment to be poisoned. Inorganic arsenic salts are now accepted by Western medicine as therapeutic agents, after thousands of years of use in traditional medicine. www.ncbi.nlm.nih.gov/pmc/articles/PMC2693900/Always remember that the dose makes the poison, and even water has a lethal dose. |

Thank you for all of the responses! I'm sorry that I couldn't get the images to upload, lol. I'm usually better than this with technology but my computer does not seem to be cooperating.
My first thought it was orpiment but I found out that it's a low MOHs and this seems harder. She attempted to test it further, nail, knife, and screwdriver barely scratch it.

I hope she wore gloves this time!  Here's your pic:  |

Truth be told, with that hardness, I’m thinking fire agate.

Ok, I’ll tell one of my favorite stories again. When the Sacramento Mineral Society was selling of as much of its rock pile as possible (in preparation for a move), I overheard two old rock hounds, as they were sorting through the pile. One picked up a rock, licked it and said, “yup, it tastes like garlic. It must be arsenic.”

Paresthesia is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause.
Common toxins that cause neuropathy include: exposure to lead, mercury, arsenic and thalium. The mineral crookesite, lorandite (TlAsS 2) and hutchinsonite (TlPbAs 5 S 9) are common minerals of thallium.

From NIH in Arsenic Toxicity: "Dermal penetration of intact skin has not been shown to pose a risk for acute toxicity secondary to poor absorption by the integumentary system. Still, caution is necessary when handling known arsenic contaminates. Hand washing with soap and water is adequate for removal of dermal exposure." |

Tingling can happen with rocks that suck up moisture, but the ones that I know are soft.
I have held plenty of arsenides and never felt any tingle. Washing up afterwards is a good idea.

I just had to take a moment to get excited that "MeMiner" commented on my post!  We love watching your YouTube channel!  |
