I happened upon several of these stones, all of which show little, if any, use. The label on this stone is wholly intact, and a stamp on the underside is visible, though all I can read is “gold medal.” The stone measures 6 3/8 x 1 1/2 x 3/4 inches. The color is not labeled, so please rely on photos. I do have a stone that is labeled light green, and this looks like the same color (this stone is shown in one photo, but is being sold separately.) There are some very light scratches, that I cannot even feel, and one corner on top has a bevel of sorts, as shown in photos. Please understand that I have no experience with these stones, so do use the photos as your guide and let me know if you have questions. Thank you!
