It looks like jasper to me. It is most common to see red in jasper from iron but it can be almost any color imaginable. The color is determined by the mineral impurity’s absorbed in the microcrystalline structure. It is also my favorite type of opaque chert. I hope to find a rare blue jasper piece someday.

It would help to know where it's from, unless I missed that some where. So many people post artifacts without locations, and the location is the most important part for identifying.
