Thanks Bfod, it's going to my nearest Finds Liason Officer on Wednesday to see if it falls under the treasure act, if so It'll get handed in and will probably be bought by my local museum. Needless to say I'll be gridding that field to see what else might be in it!

Me thinks it is a medievel or slightly post medievel " Posy Gold Ring " , if you search google you will find similar. Your do not have engraving so may be worn out or to old. Here is a link to one and Mr Potter of all names is the finder.

It has a few signatures of it being VERY OLD.

You should probably contact your local experts in the field, it may be worth multiple times its weight in gold.

Very nice find.
