It appears to be an Agate with Quartz nodule which are found in the West Country where they are locally called ‘potato stones’ because of their resemblance to potatoes! Above is an example of a small one that was self-collected by me a couple of years ago from Ladye Bay, Clevedon, Somerset, which has been cut and lightly polished to show the attractive banding inside. These English/Welsh geodes are becoming increasing difficult to find, yours looks to be a nice example.

It's locally known as potato stone.
A quartz geode with perhaps some agate.

Keep safe.

Should I clean it, and How..

23rd Sep 2020 18:04 UTCBob Harman

Quartz geodes are quite resistant to damage so cleaning it might brighten it up a bit.

I might soak it in soapy water with a bit of bleach for an hour followed by a rinse. Then soak in vinegar for 30 minutes followed by a final thorough rinse. This should brighten it up as much as might be possible with out altering the basic specimen.       BOB

Cheers bob, to me it,s a work of art, no other will be the same and will be with me forever but thought I’d ask is there a value to it?

CARL, While no values are given on this web site, you found and collected your interesting example so there is personal value to you. Somewhere, someone else might want it so there might be some value to that person.      

I don't know about UK geodes......how good do they get and where does your's fit in?

I wouldn't call it ugly, Carl. It's actually quite charming.

If those leprous white patches are a carbonate, then a bath in very weak acid like vinegar will dissolve it off.
