Featured Unusual moss agate ring

No history to this other than it had mud in the back so
maybe found by a metal detector but I’m just guessing.
A few questions please-
Does that look like a very worn coat of arms or some sort of heraldry surround?
Is that moss agate? An article I found it said that Moss Agate isn’t a true form of agate because it doesn’t have concentric banding but this stone looks like it does
Mind you I’ve only just learned that moss agate doesn’t actually contain organic material
The band seems to be formed from silver folded so there is a seam along its inner length as in the last photo. Does this method of construction date it at all? I’ve googled but I need better search terms!
Thankyou for any help

 

Does look inspired by heraldic jewellery, but that is probably a coincidence. Looks Brutalist.

Moss agate and dendritic agate don't have banding, but they are still agate.
Yours looks more dendritic to me.

Dendritic agate is named after the tree-like structures in the stone, but it doesn't have trees inside.

 

Mix of moss and banded to my eye.

 

Are you sure?

I hate when I have to burst someone's bubble, especially when it is a tree bubble.

 

Dendritic agates have no real trees in them. Darnitt. The critter at the top keeps looking at me like it's a rabbit. Maybe it's the feline in my training but I'm wondering if this wasn't a bunny ring that got the cwap whaled out of it somehow.
