Looks like one gnarly piece of jasper. The stuff we find in Oregon is a deeper red, but that is what it looks like to me.

jasper
Jasper is a common, opaque, semi-precious stone that is found in many colors, including white, brown, yellow, red, and green. Jasper is found all over the world; it is often striped, speckled, and multi-colored. Jasper has been used for intaglio carvings. Jasper is a type of quartz belonging to the chalcedony family. It is often sealed with petroleum products. Jasper is sometimes dyed to resemble lapis lazuli and misleadingly called "Swiss lapis." Jasper has a hardness of 6.5 to 7.0.

Try scratching it with a knife blade. The color somewhat resembles coral. Where was it found? With this information, someone might be better able to identify it for you.
Great looking stone/rock.

If you have a piece of quartz handy try scratching it with the quartz
Quartz has a varying hardness of 6-7

If quartz gives it a good scratch, (Quartz will scratch itself)
Try an ordinary piece of window glass
Glass has a hardness of 5

If the glass won't scratch iy you probably have a piece of Jasper, which is a quartz mineral.


Something to start with anyway.

Most people know that when you tumble things there are Gasses emitted.
These gasses would be kind of dangerous if the mineral were Cinnabar.
Cinnabar is an arsenic mineral....
Even toxic

Without being able to test it ,my guess would be jasper also.

Cinnabar(HgS)(Mercury Sulfide)is a soft material(2-2.5 Mohs scale) and does not readily take a polish.Cinnabar can be scratched with a copper penny.

I am pretty sure it is not feldspar. It would be more pinkish. Jasper takes a polish really nice. With the right tools, it is beautiful cut and carved. Great find.
