Great condition Tiffany ring believed size K +

Great condition without any obvious marks Tiffany and co ring. I am unsure of the size but based on my other rings I believe this is a size k. Gum tree will not allow me to add a photo but it is a solid silver band with T&CO on the inside and outside. Does not come in original packaging. http://www.tiffany.co.uk/Shopping/Item.aspx?sku=GRP00023&mcat=148204&cid=287466&fromGrid=1&search_params=s+5-p+14-c+287466-r+201323338-x+-n+6-ri+-ni+0-t+ this link shows the same ring except mine is all silver.
