Joshua, you should hook up with Blake Barnett. He is a super active digger in your area.

Upshur County or that general area is known to have Iron oxide (limonite, goethite, and hematite) and iron carbonate (siderite) deposits.

There is also production of high silica specialty sands including abrasive, blast, chemical, engine, filtration, foundry, glass, hydraulic-fracturing (propant), molding, and pottery sands.

I wasn't aware of amethyst but seems reasonable for a high silica sand area.

Superficially the examples resemble amethyst, but, if the location is truly "in a creek bed in East Texas", I have my doubts. I am skeptical until the id and all the other parameters of your finds are proven. No amethyst in and near East Texas and washing down from somewhere else is unlikely in a creek bed. Washing down from afar drains stuff including mineral pieces into larger rivers.

I think the photos just might be of a piece of reddish purple glass.....man created. Your photos seem out of character for the location. I repeat that I am quite skeptical until conclusively proven. Another possibility is that it is from a broken piece of jewelry. Natural stone, but man created and out of place for that location. BOB

It doesn't look man made honestly..and the location of the find was a good hike through the woods along the little cypress creek. That stretch of land has no-one for miles. I lived in gilmer TX 32 yrs and have found lots of strange out of place things there .

I would really like to see some images of that....Did you test the hardness?

With quartz looking rocks the first thing is to see if a knife will scratch it...if it will it isn't quartz.

JOSHUA, As DALE says, do some testing.

Another reason that I am skeptical is the good purple color of your finds. If you had shown rather colorless quartz with a slight purplish tint, I could be persuaded to seriously think amethyst, but while your whole example is not so special, it's strong purple coloring is quite good for amethyst.
If anything like that, with that strong purple color, were genuinely found anywhere within 50 miles, or more, of that site, collectors and commercial miners would be mining that site like those in South Carolina and Jackson's Crossroads Georgia. BOB

I would say this is a garnet, not amethyst. Based on the heaps of gravel garnets i’ve got with identical fracturing which holds together during tumbling. Amethyst pieces ive tumbled have a different refractive appearance.

Garnet i am confident. Either way not valuable but interesting.

Joshua,

Are all of these stones just as you found them, or have you had some of them polished? Or coated them with lacquer or some other finish? It's important for us to know this as we try to help you determine what you have.

It will not scratch I just put my kershaw to it.. And no polishing or shaping these are rocks that I have found and brought home cleaned in my sink and I look at them with my magnifying glass occasionally to admire and figure out what they are.. This stone is natural and glossy. Will not scratch and when light enters it it illuminates all the creveases like a light show internally

I was hoping you would try that on the other quartz looking mineral you said came from the area...this one is problematic.

So to repeat, nothing reddish or purplish like your pictures show, to my mind, is native to the location you give in Northeast Texas. I even considered SW Arkansas which is geologically more interesting; nothing comes to mind.

I will stick with my original opinion until conclusively proven otherwise. It is an old fragment of glass or, if natural, it is a piece of broken jewelry or something similar lost or thrown away into the creek. As mentioned elsewhere, this includes small pieces from an old rock collection. BOB
