They were listed as natural blue Imperial Jasper. Knew that was not correct. Hardness of at least 7. They are partially polished. Any thoughts on what they are? Some appear to be dyed. I only paid 3.00 with free shipping for all. Thank you.

If you don’t get an answer. I’d just call them Smurf stones.

The ones at 2:00 and 6:00 look a little like K2. The one at 10:00 looks familiar, but I'm having trouble accessing the brain cell that stores that information. Could be so-called "Sea Sediment Jasper" (aka, limestoney stuff dyed by the Chinese).

I'm thinking sediment stone, too.

Thanks everyone. I liked the colors and patterns. The price was right. Once it warms up, will be taking them to the wheels for shaping. That will tell if they are dyed and if the dye goes all the way through.

Wow! The price was right! That doesn't even cover shipping. Dyed or not. These rocks were a steal! I can wait to see how you transform them in to something nice. I can only imagine.

That will tell if they are dyed and if the dye goes all the way through. You can also test for dyes with acetone. Dip a Q-tip in some nail polish remover and rub on the stone. If you see blue on the Q-tip - you know for sure

fernwood did you find out if they were dyed or not yet?

fernwood did you find out if they were dyed or not yet? Tried testing with acetone fingernail polish removal. No color came off.

I have seen that labeled as sediment jasper out of Indodnesia. Indonesian sellers blow up my IG and FB DM/IM with pictures of it all the time www.facebook.com/2404292819794537/posts/blue-sediment-jasperavailable-for-saleif-you-interested-in-buying-it-please-sent/2404957156394770/"Sea Sediment Jasper - Not to be confused with Sea Jasper (as it’s another name for Ocean Jasper, which is a real mineral), it’s also sometimes called Emperor Jasper. It’s a mixed bag, but the majority of sea sediment “jaspers” are man made dyed resin/polymer creations. However, some sellers dye other minerals and sell them off as sea sediment jasper. Some number of dyed stones include low grade variscite, agates, and (in one case) white brecciated jasper"

MsAli Thanks. I took a chance buying, as the price was right. Since both the acetone and hot needle tests were negative, I tried using a diamond fingernail file on the edge of one. Was able to get a tiny area that I could smell. Did not smell like resin. It is pretty hard material.

Hope it turns out well. Would love to see that blue all polished up and shiny.

Here's a post from a now-defunct gemology forum that deals with this material: Gemadddicts Forum. The same man-made composites have been sold under many names, often as natural materials such as Gem Silica, variscite, jasper, etc. (here's a mindat post where the same material was misrepresented as turquoise: mindat). Colors can vary, depending on what they want to imitate or produce, with copper green-blues being one of the more popular and easily produced. Ebay, bead sellers, etsy, etc. have been flooded with the stuff for a decade. Depending on which type of "sea sediment" stuff you get, it can be resistant to most old-fashioned tests such as the hot pin, acetone, and similar. The people who do treatments have become very sophisticated at dodging the easier tests. The harder type have all turned out to be a sedimentary marble-like material that had been dyed and treated with sealants. As said, there are a few manufacturers of this composite material coming from China. There are some microscopic pics of another type on page 499 in this that shows how dye tends to pool along fissures, porous areas, and similar weak spots.
