Identity HelpBloodstone? Agate?

4th May 2015 17:58 UTCAnonymous User

Found this in Minnesota on the shore of a small island in the middle of a lake, found a couple more pieces like it. Variety of dark purple & redish purple with lines running through it (better visible wet) looks like some quarts, there is one spot with a spec of bright red on the first rock.


I kept asking around & everyone was telling me its bloodstone but what do they know right? thought i would get the professionals opinion on it :)

Well, you definitely have chalcedony (microcrystalline quartz), but I wouldn't necessarily call what you have bloodstone. Rather, it appears to me like you have some chalcedony with iron inclusions to give the entire piece a red colour. Classic bloodstone would be green with red spots. Looks like a good cutter piece for lapidary purposes.

There is no bloodstone police, and since blood stone is a well known term and has some value attached to it, people have used the term to sell all manner of rubbish. Generally the term refers to very dark green jasper or chalcedony with tiny red spots scattered more or less uniformly through it (mostly from material from India). People use the term loosely for agates and jasper that are red and green mottled material and some even more indiscriminately than that.
