Featured Not a rock hound please help ID this stone

Hi Everyone ! I'm very bad at IDing various stones, is this Ocean Jasper ?

 

Yes, could be ocean jasper, although that grey area looks like chalcedon, in which case it could be (dyed?) agate with a chalcedon inclusion.
Ocean jasper:

Chalcedon:

Green and yellow agate:

 

Morning, AnyJ! Your top photo looks like something on a slide under a microscope!

 

AnyJ, thank you for the help. Everything you just said is Greek to me. If you were to sell this ring what would you call it ? It tests just above glass in my gem tester field.

 

It does, but I don't think it is contagious.

 

Maybee Onyx?

 

Chunky sterling silver and agate ring.
I am not entirely sure about the agate, maybe someone else has a better idea. Jasper, agate and onyx all have roughly the same hardness, just above glass.

 

I don't belive it's jasper. I just did some looking and Wiki says "agate has curved bands and onyx has parallel bands." So it's probably not onyx.

 

To complicate matters, this is also onyx, no parallel bands:


Calico, for now I would call yours agate.

 

It appears to be Jasper with an agate inclusion.
I would simply say Jasper and sterling ring and not clarify what type of Jasper.
Too many to name

Thank you !

 

The inclusion is chalcedon, not agate.

 

I would clarify. In jewelry, there may be different usages, but in mineralogical terms, "Chalcedony is a generic name given to materials that are composed of microcrystalline quartz. Agate and jasper are both varieties of chalcedony....agate is a translucent to semitransparent chalcedony."
If there are bands, it is likely agate, though other kinds of chalcedony may also be banded. It depends on the degree of translucency, though "observing bands in a specimen of chalcedony is a very good clue that you have an agate." With a small inclusion, in a photo, it is probably not possible to differentiate agate and other types of chalcedony. But they are basically the same material. Jasper is the same stuff, but opaque; and they are all varieties of quartz.

This is very likely jasper, and the inclusion is some kind of chalcedony, likely agate.

 

Thanks !

 

I generally just call something like that RPR - Random Pretty Rock - and don't worry about it much. I agree that it's some form of agate though. It has the wrong structure for fossil bone or fossil coral.

 

Gorgeous, would love that ocean jasper in a ring.

 

Yes.
I've done some rockhounding, and collecting of beach rocks; and it is often not possible to tell exactly what something is; and beach rocks may be mixtures including several forms of chalcedony; jasper, agate, quartz often occur together.

 

@all_fakes
Thanks for the rock tumbler link. I've bookmarked it.

 

Yes, chalcedony is the basic stone, grey, whitish grey to bluish grey, usually banded.
When other minerals are added to the chalcedony, different colours are produced. Then it becomes agate, or in some cases jasper.
The inclusion in this stone is grey with whitish grey, so the inclusion is chalcedony.

 

@all_fakes .....that link is great!! I checked it out as I have a ring of my Mom's that I wasn't sure about (will post in separate thread!)....looked at "Polished Stone ID" and there it was!!!! SO helpful!!!
